Trying to help:
Important bugs to be fixed that probably everyone knows:
If you speed up the game too much the game glitches and dies with a black screen.
Also the names move to an upper position by the same way.
If you offer military access to a civilization that's at war against you will run over you but you won't. (I don't see the offer military acces option very useful idk)
September goes before August (in the game)
In some point of the game, when therelations with a country reaches 0, it will mantain in 0 the rest of the game.
The countries you create won't be added in "age of civilizations" mode (not important but everyone knows this)
Bugs that happened to me:
when i move the position of the port the game breaks for ever (need to reset).
Sometimes rebels becomes a civilization called literally rebels and on every turn (sometimes two or simply stays) changes. I don't know how to produce it. Usually happens when i use the spectator mode.
When you share an enemy with someone and this someone has troops in your land, if the enemy attack theese troops they will simple disappear. this also happens against two enemies that are at war with you. only the troops of the civilization that hosts the province will defend.
I'll update this list through time.
When a province is colonized, it shows on the right side of the screen, but if the name is too long will only write the end of it's name
