for @CaelReader

added
48)Pre-1.6 Bug: The game can erroneously attempt to exile someone twice
49)1.8.0 Bug: The new Sepoy Revolt Event spams errors

old removed fixes:
1)The Cohesion of Ideological Union will now behave properly
2)Earning recognition is no longer easier with bad SoL/QPDc
3)St. Basil will was in Mazovia
4)Manor Houses no longer costs infrastructure
5)Persia no longer gains claim on the wrong Georgia, General Brusilov's recruitment criteria also require fully owning the correct Georgia.
6)Lowered tech requirement to Nationalism for earning recognition (Colonialism in official hotfix)
7)Minimum Worker-Owned Levels for Agricultural Buildings while under Homesteading is now 75%, up from 50%. To bring the share-split in line with 1.6.2 numbers (confirmed nerf/buff)
8)The PM of Freedom of movement principle no longer grants countrywide migration attraction
9)Pre-1.7 bug, but when unrecs make a coladm (colonial puppet) it will become independent
10)1.7.1 wanted to lower GP relations requirement for recognition to 50, but didn't. So i did it for them.
11)1.7.0 Bug: Cotton Plantations erroneously still employees clergy, they didn't get the memo that they should chill at the crib (manor houses)
12)1.7.0 Bug: a suspected typo for the third tier of rice farm PM, it should cost 20 fertilizer instead of 30. Because 2*10=20
13)1.7.0 Bug: Confucian Devout getting the "Be Fruitful and Multiply" trait.
14)1.7.0 Bug: Collectivized Agriculture didn't do anything. Now it actually Collectivizes the Agriculture.
15)1.7.0 Bug: A (probably harmless) missing bracket in the slavery law file.
16)Planned 1.7.2 Feature: leverage resistance from population now halved.
17)1.7.2 Bug: Collectivized Agriculture forgot to collectivize the ranches.
18)Workaround for 1.7.2 Bug: Erroneously cannot upgrade power bloc primary principle...
19)Planned 1.7.4 Feature: Japan is playable now (Honorable Restoration improved)
20)1.7.2 Bug: Using nitroglycerin on gold mines was supposed to give you half the gold of the dynamite PM.
21)1.7.0 Bug: Three instances of "exists = yes" which were generating errors.
22)1.7.2 Bug: Only Japan with enough GDP was ignoring the world. Instead, all big isolationist countries should, and Japan should stop doing so after they end sakoku or became too small
23)1.7.2 Bug: Due to a typo, no one can befriend anyone if they are non-isolationist OR has less than 5M GDP (read: basically everyone). Instead nations should not want to befriend big isolationist countries
24)1.7.0 Bug: Two ideologies (Authoritarian and Despotic Utopian) was supposed to be a conditional replacement for Vanguardist. 1.7.0 moved the tech criteria for Vanguardist to Political Agitation but forgot to do that for the other two
25)1.7.2 Bug: Similar issue to 26) but this time it's antagonize that is bugged. Instead what should happen is nations should not want to protect big isolationist countries
26)1.7.4 Bug: AI wanted army size from population is erroneously capped at 2000 battalions. Should be 200 instead.
27)Fixed Suspected 1.7.4 Bug: Slavery Laws where given LO clout buff again, but Debt Slavery got the +50% instead Slave Trade, which is very unexpected. For now I'm swapping these (which is how 1.7.1 did it)
28)1.7.4 Bug: When a subject has over 25 Liberty Desire, you erroneously only need to pay 25% of the infamy for any diplomatic plays you use on them, instead you're supposed to pay the full undiscounted infamy amount.
