I recently finished a mod using MCreator 1.5.4 and exported it. The mod was created for, and ran on, Minecraft version 1.7.10 with Forge version 10.13.2.1291, which is the current recommended version. The mod worked perfectly in a MCreator test world, but when opening it in Minecraft, I recieved a black screen instead of the Mojang screen, followed by an immediate crash.
Mod can be downloaded here if you would like to try it out for yourself, but it is still a work in progress.
The crash report can be located here.
