Yes. It will reset your spawn all the damn time (took me forever to find out what mod was causing the problem).  I removed the Tropicraft mod from my server as well as a few others that were causing issues.  no one really cared about the ones I removed.

 

I have had a lot of issues with galacticraft as well. I haven't been on much since I installed the latest update, but I haven't had any complaints as of yet.

How screwed will the map be if i delete galacticraft?

Im not an expert, but one of my players says this means a Galacticraft thing is putting stuff into a Tesseract, and it does not like that. Crashes any time someone walks into the chunk. 
Anyone know a way to stop this from happening? 

Also, less importantly, do Tropicraft portals reset the server spawn on your servers? Because they sure as hell do on mine. This is Vanilla AOBT with nothing else in it or changed.
