Which remaining gamebreaking issues have I missed that is not one of the three I listed for "needs more than a patch" ? My eyes must have a special filter making them miss the multitude of other issues raised continually (for example, I'm sure your post is friendly and gives a couple of examples, my eyes litteraly stop me from seeing them)
Lets quickly go through the Leviathan feature list:
1. The favour system was bandaid fixed with a cooldown instead of actually balancing the favour gain rates.
Not balanced properly
2. the new regency events unintentionally break personal unions and cause other issues.
Broken
3. The new colonial nation types don't apply their effects properly, some aren't applied at all, some with wrong values.
Broken
5. Concentrate development was designed for tall play but is almost exclusively helping countries with a lot of wrong culture land, therefore wide play.
Feature is not achieving intended goal
6. Pillage capital is the least "non working" feature. Although it's balance has been a topic it is not actually broken.
7. expand infrastructure is useless. It is never used. Wide countries cant afford the GC cost and tall countries don't need it.
Feature is dead on arrival
8. Centralize state is a weak copy of the already existing mechanic "expand administration".
Feature is dead on arrival
9. Totemism works i guess. Didn't check much tnh due to the state of NA.
10. Monuments still have multiple impactful bugs lile forming a new nation preventing you from speeding up the improvements you already started as the old tag. Most issues aren't gamebreaking with this feature but still issues that should not exist nontheless.
11. The minor QOL stuff seems to mostly work.
Now on to the imortant issues of 1.31 itself:
1. performance is unaccpetable. Especially the state notification issue (blue flag issue) completely kills the game.
2. Native reform gain is still way too unbalanced. AI colonisers often fail completely to colonise the east cost and i have seen multiple games where colonisers fail to get a foothold until they come from the west after colonising SEA.
Now
ALL the issues mentioned here are content for patches. Nothing here is about stuff that needs reworks in later branches, all of this can, should and frankly
must be resolbed within the 1.31 branch.
