I'm using this patch along with the official 3.17. The Solver patch was installed via the installer by Grumbler, and I'm using the BUG mod. When I enter the custom game screen some of the options read as

TXT_KEY_GAME_OPTION_LEAD_ANY_CIV
TXT_KEY_GAME_OPTION_NO_TECH_BROKERING
TEXT_KEY_GAME_OPTION_NO_EVENTS

and the espionage screen displays some similar writing, overlapping other words on the screen.

So my question is, is this a bad install where I have to reinstall everything?
Or is there an ini I can adjust or something, to get the options reading like normal?

Just get the latest version of BUG, that should do it.
