We found source of the problem, in 4.13 we created Actor (BP_AIMarker), which we used for our AI.

In “Construct Script” of that actor we creating dynamic material instance for “Text Render Component”, and this is causing the crash of the editor when we change maps in UE 4.14.

It’s 2019 and I’m still having this crash.

I thought this technique was correct, until I tried it again and it failed me. The better fix seems to be: close all open pop-up windows (especially if a last session was restored) > move an object in the scene back-and-forth (not exactly back to its original location, but nearly the same) > save the current level > open a new level.
