I get a General Error when trying to start a game with at least one Taidan faction on the map. Also, it's inconsistent, but some games will start without displaying the number of RU's, Research Score, and rank score.

thanks for the report, when this happens can you copy paste here your log? you find it in homeworkdRM/bin/release/hwrm.txt
you shouldn't experience these issues, installation is ok?

i got various crash

All is pretty normal, attach the rest of the log when you have it, anyway, if the crash persits unsubscribe, delete the complex folder, close/relaunch steam then subscribe again: in case create a new game profile. I presume you're running Complex without other mods and/or addons

i have supp all files and re download all , delete other mod ( 4th tactic view / silence tatic map ) appear with the reinstall and don't touch any language but select english in steam ... and now it's run like a charm even on my old 5870 :D need to learn taiidan now :3

Many of the buttons do not appear to be functional, including the options and player profile buttons on the main screen. All other mods disabled, and a fresh install of 11.4.3.

The "Research Level" feature is bogus, previous version's research mechanics is far better then 11
