Woah, you're right, the zip file is empty. It's 170 bytes now... I always check my file sizes and I'm certain it was in the KBs when I uploaded it yesterday. This happened with another mod too where the jar file mysteriously disappeared when I uploaded it to GitHub, pretty strange behavior.
@Blacknsilver,
I can't reproduce this bug. Just to be clear, you are on Starsector 0.97a-RC11, correct? This could happen if you're using an older Starsector version, if FleetEncounterContext is different there.
@Polite Pufferfish,
Can you be more specific about the nature of the bug you're encountering and how it's being triggered?
Edit: added a hotfix to address the empty zip folder issue and to apply a tentative fix for older SS versions / versions where FleetEncounterContext is different, which would potentially cause the issue Blacknsilver mentioned.
