The game crashed whilst rendering overlay
Error: java.lang.IllegalStateException: Failed to load description for particle livingthings:arrow_up_green
Exit Code: -1

first, not that much of a helpful bug report

• What mod version do you use?
• What forge version do you use?
• Crash report?

second, someone else already reported the same issue previously

• not the fault of my mod in particular
• it seems there are some incompatibilities between my mod and others

and yeah, i'll probably remove my custom particles
