So I wanted to use the updated file with the cherry trees but it crashed the game just after clicking play on the launcher. When I switched the mod version back to the previous file, it stopped crashing.

• Forge Version: 31.1.18
• Mod Version: FruitTrees-1.15.2-1.2.0.jar
• Can you reproduce this issue with relevant mods only?: yes

here's the crash report:

Just downloaded it, still crashing:

Do not know why, but should be ok now

please try to re-download mod file from curseforge
