Describe the bug
An old version of the mod can be loaded on newer MC versions. It does not work, but Forge does not explicitly say it is outdated.

To Reproduce
Take the 7.0.1 release, and load it on 1.15.2 Forge.

Expected behavior
Forge should deny loading our mod on the basis that it is outdated.
