Hello,
I am back with the feedback.
I think I found solution, I didn’t need to reinstall the editor.
So what I did is I turned back on OODLE plugin to make things worse and investigate this matter (previously was worse with it ON, way more occasions of braking material).
After doing that, I worked on my project for about 3 days and it didn’t happen again, I have tried to replicate the issue of braking material but it didn’t happened.
In my case turning OFF and ON OODLE plugin helped me to get back on track, I am not saying it is solution for everyone, but for me it somehow worked and problem seems to be eliminated.
I will update if it going to change but so far it looks alright, I have tried in other projects and all works good, I can not even say what was that, I struggled with it for quite a bit.
If you still have the problem, please try to turn it OFF and ON and see how it goes.
Good luck on your development!
