[simon9664]

Im using a forge 1.7.10 server with a mod for 1.7.10 in a .zip. The mod makes the server crash. The mod works in singleplayer but not on a server. Here is my log

I remove the mod and the server doesn't crash.

[simon9664]

I am the author of this mod. When I export the mod, the program I use exports it as a .zip. There is no way I can export it as a .jar with the version I'm using.

[galaxyoyo]

Does the crash appears on client ? I've got this bug, the problem was I used the Minecraft.getMinecraft().thePlayer, and it returns a EntityClientPlayerMP. On server, this class doesn't exist, that's why it makes crashes. I think it's not related to the zip format. This is deprecated, but I think it works. But the jar format is better, and Forge Gradle uses this format, why do you convert it in zip format ?

DO NOT use MCreator -.- If you're gunna make a mod, then make it.
