bump

Also, please use pastebin for error logs and stack traces.

Mod list, please; and a description of how the error occurred. There's very little helpful info here.

I found Dynamic trees crashed as well. Have attached crash report.
crash-2020-05-18_18.06.02-client.txt

Downloaded it a second time and it worked that time.

Added a null check that should fix the problem if whatever conditions re-emerge.

Latest curseforge download should resolve this issue.
