I suspect the crashes are due to loading an object from a modpack that is not compatible? I'm am not well-versed in reading crash-logs but to me it seems to be pointing towards Apotheosis causing the crash. For example, I assume I loaded a chunk with an imcompatible mod and crashed the server, which requires that I restart the server (I was given access as a subuser), and as soon as I load in the server crashes immediately, not allowing me to traverse away from the problem area.
Is anyone else facing these crashing issues on DawnCraft?
