Cherry Tree Crash

[Tenyearoldkiller]

I was playing on a server my friend made using your modpack, I was attempting to use the ancient warfare tree farm and put hill cherry tree saplings inside of it and it crashed my game, thinking it was just my computer I restarted Minecraft loaded in and try it again but to no avail. After thinking for a minute I logged back in and tried dropping the saplings in front of the tree farm and it crashed the server. I have the crash report for my game crashing but I cannot get the server crash report
