I try to avoid saved games incompatibility but sometimes I remove a feature again because not every new idea turns out to be a good idea.
It's one reason why I don't bother playing on large maps anymore, because I constantly like to tweak on settings which possibly screw up my session.
This time, it was the Barbarian Mech. I know not many like the Giant Death Robots, and I also think they somewhat out of place compared to the rest of the available units. My mod doesnt offer any additional future units and possibly never will due lack of new unit graphic. The Giant Death Robots available to Civs already need 3 resources now what makes them more like prototypes. It looks silly if Barbarians have a lot more available than any Civ then.

No idea what you mean. I just did two quick games with v20 without any other mod and together with TBC v72. Spaceparts dont receive any levels or promotions.
There were certain minor incompatibility issues with v19 and the last few (beta) TBC versions but those should be gone with v20 (until tomorrow when the next beta build arrives

)
Dunno if the issue above has/had something to do with TBC, but some TBC features, for example my increased Barbarian spawns and the TBC-Germanys ultimate conversion trait dont work well together, so I have to put a damper on the TBC settings sometimes.
Or the Spoils of War policy feature of TBC-Honor tree is also giving way too much gold per unit at moment what can easily be exploited by farming barbarian units. I like to fence with Barbarians, so TBC features have to go once in a while.
The problem is that I often cant adjust new implemented TBC features without blowing up compatibility to vanilla. The game hates meddling with parameters that dont exist, even if I add an "exists TBC feature x" condition, hence I have to completely delete and replace TBC stuff with vanilla or own features. Ive never bothered to learn LUA programming so far, so my possibilities are limited.

TBC isnt really slowing down the game start or loading games that much. It gets really slow if you add many custom wonders, R.E.D. modpack, and Building Made Fun.
You could delete or put an underscore to the folder name of "TBC - Thals Balance Combined" and play only with "CiVUP - Civ V Unofficial Patch" from Thal. Then you play at least without any other bugs.
I included Barbarians! because its easier for me to manipulate all (my) units then in one mod.
Native Terrain is such a minimod without much gameplay impact that I also added it to shrink the mod browser list. Its settings also help sometimes to get civilizations and their unit features onto the proper terrain.
Native Wonders will never be included to UT or any combo-pack because it makes a too drastic change to wonder building. It turns wonders into Civ features where others could complain its totally out of balance; and they are probably right. Its just a personal taste of mine to get rid of the wonder-race.
Building-Mods like "Building Made Fun!" should work together with UT because I dont really change technologies, only connections. I tested it a few versions earlier. Im not sure right now if my latest v20 changes could have messed up something in combination with this building mod.
I tend to play with TBC, therefore I havent tried other building mods so far. Its quite tricky to get TBC running together with other mods, especially if there are daily beta updates people like to play with.
Units and combat alone takes a lot of time that I havent made any building changes yet. Actually, I dont feel the urge to do so because I rather enjoy unit action.
I guess Id have to create a new mod with a new name then if I start to change buildings too.

If anyone has building-suggestions related to units then Im fine adding those to UT too.
I once created building requirements for units but this gets too fussy. For example, Factory needed for more or less all modern mechanical units. In the end, I had created so many restrictions but basically gained nothing. City States would have been crippled too much, and it wouldnt have been a lot of fun anymore playing on small map sizes with less resources.
The AI, responsible for unit action, is also something Id like to see improved like everyone else, but experimenting with that is also very time-consuming.
Okay, enough words for now.
