Today funny thing happened. Electricity in our whole street went away about the same moment as i was launching devmode, if I recall it correctly. I turned on PC soon after electricity came back. But at first there were no internet, so I ran steam offline mode (I don't know if thats important). The devmode now simply doesn't launch at all. And +ptool, +ttool doesn't launch too. Bin64 folder shortcut doesn't launch it too, it launches the launcher. Old UI. The main game works. Been trying many things: steam restart, computer restart..... Nothing helps. Any advices what to try to solve this ?
Verify rF2 files in steam. If that doesn't work, just rename the entire moddev folder and verify again. It's not too big.
Thank you. Verifying did work that time when moddev folder got renamed, indeed an issue must have been in some files there. Strange how sudden loss of electricity caused or took part in causing an issue there.
