[4.12.5] Can't Interact Properly With Editor

Suddenly, and without reason my version of 4.12 became almost unusable due to the editor simply not recognizing button presses except in very rare circumstances. Not only that but Blueprint also begins to seemingly lag. This is only happening with 4.12 as I also have 4.14 installed which works fine.

Hey Galdard-

This is likely behavior that was an issue in 4.12 as you mentioned but was addressed and fixed. If you’re able to use 4.14 without running into this behavior I would suggest continuing to use that instead.
