I removed the mod for now, I need to go live by Friday but I hope this is something that can be resolved so I can add it back to my server. Thanks for your hard work.

can you try with 7.99.15-pre4? that has improved logging but i suspect this is a case of you having content mods on the client that are not installed on the server (#3990)

I'm sorry, I'm needing to launch my server like today and don't have the time to test it myself. If nobody else has the issue I can cross the bridge later when I try to get it live again. Wanted to give an opportunity to see if it was on your side and make you aware of it. Thanks for your consideration and great work on an awesome mod!

It's been an issue before (for example the linked issue), however we'd like to see if the same fix that worked for that also fixes this.

Thanks for reporting though, hopefully when 7.99.15 actually releases you won't encounter this again :)

any update on this? does the bug still heapen if the client and server have the exact same modlist (and versions)?

closing as this is almost surely a duplicate and no more info was provided
