Sorry for short description of the error.

The game crashes on startup when installing Apotheosis with DynamicTrees:

The developer of Dynamic Trees is not particularly engaged in solving the problems of this mod. Apparently, I'll have to fix it myself. Sad :c

For whatever reason the garden module effects dynamic trees. If you really want both installed you can disable the garden module in apoth and DT will work alongside it.

Edit: This sounded like a smack at apoth, by no means is it. I find it odd DT code relates any way to the garden module considering that is cactus and sugar cane.

Posting Here as the issue is still open and Dynamic Trees does work with Apotheosis and Placebo as long as Optifine isn't installed.

Dynamic Trees Throws
"/ by 0" crash on startup w/ Dynamic Trees & Apotheosis/Placebo

[Follow up.
MC: 1.12.2
Forge: 2836 (Issue encountered on an earlier version, but suggested by mod involved "Apotheosis"

Minimal list of mods to reproduce.

Dynamic Trees 0.9.5
Apotheosis 1.9.4
Placebo 1.6.0 (used by Apotheosis)
Optifine: Encountered w/ "preview_OptiFine_1.12.2_HD_U_E4_pre4"
Additionally tested against "OptiFine_1.12.2_HD_U_E3"

This was tested without VanillaFix for the same outcome, then VanillaFix was added for convenience with the hastebin (link) which replicates the above report.](DynamicTreesTeam/DynamicTrees#254 (comment))

I think I'll close this now. There's literally nothing I can do about it on my end. I don't even edit the texture for sugarcane, so it's really weird that it happens at all.
