use MOD list

- harmony
- Core + DLC
- ModularWeapons
- ModularWeapons - Expanded

Does this error crash your game? Does this error only appear when using ModularWeapons - Expanded? I will take a look sometime to see if it may be an error on my end, otherwise it could be the base mod ModularWeapons causing the error.

the quest is not generated correctly and cannot be deleted.
This does not occur with the base MOD alone, but only with this add-on.

but after, I also reported it to the author of the base mod. he issued a fix (:
If it happens again, I will contact you again.

Yes, please let me know. I don't touch anything regarding quest generation. The only thing I can think of is a gun not generating properly as a reward and breaking the quest.
