Hey @Cosmonauth, I used your file but no luck I still get he same serious warning. Maybe it's not a big deal afterall, I've build a few ships with OPT part and no issues yet.

@Cosmonauth I tried deleting OPT_B9PS : creates an B9Partswitch fatal error on startup. I deleted every !Kerbalism in OPT_B9PS : no crashes but the problem is still there Then I tried replacing every !Kerbalism with Kerbalism and it works ! I can select every ressources (even waste and weird gases i don't know if that's normal) in my OPT fuel tanks. However I get a serious warning on startup. https://imgur.com/fwyeT6G How do I take care of it ? That looks scary.

Hey, Thanks @Cosmonauth ! Here's my module manager logs : https://drive.google.com/file/d/1QfJtV4Pi3Kln5JPgRjU3_UpEmvkAkhA-/view?usp=sharing

Hi, I have some kind of compatibility issue with OPT and kerbalism. When Kerbalism is installed alongside OPT, everything from both mods works just fine except the OPT fuel tanks. They appear without any fuel in them and no options to choose one. I tried uninstalling all my mods expect OPT : it works great. Then I added mods back until I found a problem and I deduced that Kerbalism was the problem. I tried installing only OPT and kerbalism and yeah.. same issue. I'm running KSP 1.9.1 btw. Can you help me figure it out please ?
