okay, I guess this will be my last post here for a while seeing as Leoreth seems to be too swamped to deal with all the bugs, so all these things are probably really low on the priority list, anyway:
1. The Indonesian UP is pretty useless, I played 2 games where I made <50 gold total until 1500AD with it (had to abandon the first one due to update with Canada, 2nd one is bugged and the bug is not yet found).
It is a really nice and cool UP, but it just doesn't work out in most cases.
After 1500AD the 5gold are not really noticeable (compared to the total amount of commerce you have) so basically the UP gives ~0.5% more commerce over the course of the first half of your game.
Also the Indonesian UU sort of counters the UP since it sinks enemy ships which otherwise could - maybe - one day pass through your territory.
Still, I like both, the UP and the UU but the UP is just so incredibly weak that it is barely noticeable.
2. Your approach to stability feels really unfair. Almost no boni for "good" behaviour, only mali for "bad" behaviour. Removing the stability from trade and decreasing the stability from open borders without any compensation since "trade routes are basically determined by open borders so you get rewarded twice" might be logical from your point of view but just removes 2 pilars of stability. Military can't be kept positive, neither can expansion, and domestic is pretty negative as well.
In my current game with Japan I am running 90% culture (to meet the UHV) thus have >20 happiness in every city but still only get a +4civics-4unhappiness (probably due to whipping) in the domestic stability column.
I have 10-15 more happy faces in my cities than unhappy ones and yet I dont even get a bonus that nullifies the whipping unhappiness. And now the stupid Incas let their cities grow, thus collapse and cause crisis after crisis in my empire, yay thats fun -.-
3. What do you think of changing the Spiral Minarett to "+1 gold per islamic building" (instead of: +1 per state religion building), this would allow the Arab/Ottoman-civ controlling it to switch to Free Religion in the later stages of the game and makes it less of a target for the human player (since your catholic temples won't all of a sudden give you gold when you conquer the wonder)
4. The Slavetrade mechanic is still somewhat buggy. Mansa & Mbemba will give you the slaves for free (or 3/13 gold) if they think you can't use them but you can sell them for a lot of gold to the Euros or settle them in your American/African cities (only 1 per city now?). Give them a minimum value for trades, so they always charge you either 25 or 50 gold for them, to make it a bit less of an exploitable mechanic without removing its impact.
