I found that this mod is the reason for the crash client under Windows. Tested in singleplayer and on one Russian server (with admin help)!
I have tried several clients under different systems: win7/win10 x32\x64 ver 5.6.0 , 5.6.1 , 5.7.0
Maybe the reason is in the Minetest, I do not know.
I really liked this mod. The bushy leaves are advantageous over boxy as they are kind of opaque, have uneven hitboxes. I am saying that it is worth to be tried and these properties might help in making a trap.
