I didn't have a chance to try this, since I tried alartor's recommendation first and it solved my issue. So it's possible this could work too. Thanks for the suggestion!
For KSP, I'm running 1.10.1 and for KAC, I'm running 3.13. And in looking at this, I just realized my issue: The KAC mod is updated for KSP version 1.9.1. Thank you helping me realize my own mistake!
I've recently had trouble trying to load Kerbal Alarm Clock. I first started playing KSP a few weeks ago with no expansions. Kerbal Alarm Clock was one of the first mods I tried and it was working great. I recently bought and installed the expansion packs and noticed that the Kerbal Alarm Clock wasn't loading anymore. Is it because of the expansions? Or are there other common mods that aren't compatible with KAC?
