All tests done with
Minecraft 1.12.2
Forge 14.23.2.2611
Rustic 1.0.0

Client crashes when Dynamic Trees 0.7.4 is installed

Client does not crash when Dynamic Trees 0.7.5a is installed

Server crashes when either Dynamic Trees 0.7.4 or Dynamic Trees 0.7.5a is installed (didn't test earlier versions)
DT 0.7.4: https://gist.github.com/Lorelando/9ae47db8a0b571299f12a4a9af9f35f6
DT 0.7.5a: https://gist.github.com/Lorelando/4316e46737abecd896a376904a2afc97

The client compat requires 0.7.5a (or probably higher, until a future Dynamic Trees update breaks the current compat). I just fixed the server crash, and released an update on curseforge. I've also made sure that attempting to use a Dynamic Trees version below 0.7.5 should actually notify the user that they need a newer version.
