well i don't know that much about programing and what not but they seem to be lua errors and the only mods i know use lua are computercraft and ccsensors.
everything i have looked up suggests it is one of those two mods
i just also want to point out another bug where your game would crash if you opened an alchemical chest with a bunch of tools in it. Happened to one of my chests and some other trainees' chest i think. Not a huge deal but it had never happened before

Suggestion for the server: make a wall or something that lists the useful commands. /help only does so much. Multiple resource portals (spread us out a bit more)? Make the rules easier to read, seriously that trippy rainbow tunnel with glass infront of signs is distracting.
