Some more input, this time playing as Amurites (with the usurper leader, if that matters for the buggishness). Again, some stuff might not be bugs, but things I just don't know about ^^.
Leader shouldn't matter, though I'm not really familiar with that one; Merged it from Iceciro, and haven't gotten around to playing him.
- Tooltips for the whole Force promotion/skill tree, as well as related abilities need some attention. Almost all are empty.
Agreed, we're working on things like that.
- Had a stonewarden able to summon Djinns (instead of Pegasi?)
No idea, will look into it.
- Can build enemy capitol buildings with the usurper trait. Didn't do it, but would it change my faction, to e.g. Calabim, if I did?
Would not change your faction, but your palace would be removed.
- Had all kind of units starting out with tier 3 spells (from wizards tower and govannon school i suppose, but those should only grant tier 1 and 2). Including units that don't know how to cast. Most amusing was my workers that seemed come up with Fire III a lot.
Not a bug. Mage's Guild/Cave of Ancestor's/School of Govannon allow it, each one allowing the next tier. It's a feature specific to the Amurites.
- Mithril Golem gains exp, but has no possible promotions to spend the levels on.
All golems work this way. Except for the golem hero, Barnaxus.
- Can't build evangelica mandaciums in the capitol.
This is one I don't know about.
- Could promote my Stonewardens (tier 2 priest) to tier 3, even with the usurper trait (which I shouldn't be, according to the drawbacks of the trait). And it wasn't the money-priest-thingy, but the normal upgrade.
No idea; Again, not familiar with the leader's mechanic.
- Man-o-wars/Frigate stacks have the same range bombardment bug as units in the same stack as bow of the long-sighted.
Yep, it's a universal issue, not limited to the bow.
- Slave (from kuriotates i think) were able to upgrade into a berserker (but nothing else).
Will check it out.
- Feast (vampire ability) doesn't work, even with the usurper trait. Since other abilities do work, that otherwaise are civ-restricted (like build palace, dwarven fortress, and civ-specific units), maybe this is a bug? (vampire was in former calabim city)
Feast is Calabim-only, and done intentionally.
- Auto-upgrade promotions frequently didn't work. Most notably wall defender, and from another game the haunted lands buff as Scions. Got the promotion for manual upgrade though, so no biggie.
How do you mean, they don't work? When I use them, they show up as soon as reqs are met.
- Invisible tower mages (from nox noxis) won't stop barbs from entering the square and pillaging my dwarven fortress.
Side-effect of forts not having the bActAsCity tag; Planning to add it.
- No automatic war declaration from the last opponents to prevent Altar victory (like a Tower Mastery would trigger). They were kinda in love with me though (atleast 15+), but they just sat still and watched my borders while I won.
They may understand it better next version; Snarko has taught the AI to pursue that victory.
Might as well answer to a few of them (the ones I'm sure about), this way I'll save Valk a few minutes which he can then spend on bringing out the next patch faster

.
Heh. Next patch is coming along; IDW is done, so just the Barb system (nearly done), Sidar (Opera is taking over that one), Mechanos (minor things, aside from removing Ordo), secret addition, and then art/music.
For a reason I never really understood slaves can be upgraded to Berserkers (and lunatics if you're following the Overlords), I believe that's something inherited from base FFH (might be wrong though).
I actually didn't know that one.
