Ctrl+z crash with move of static mesh [Linux][4.14][Bug]

eWomerOC · October 12, 2016, 5:06pm

Only moving static meshes and clicking ctrl+z to undo the move will cause a crash. I can add materials, and undo that and move the player start/Third person char and no crash. Product version is actually 4.14 but the option, as of this report, was not there yet.

Core dump file.

Hey -

After pulling the 4.14 branch from GitHub I created a First Person template project. In the default scene I tried moving the boxes around with the transform gizmo as well as placing new static mesh boxes and moving them without a crash when pressing ctrl-z to undo. Are you able to reproduce this crash in an empty project and if so, can you elaborate on how you’re adding/moving your static meshes?

eWomerOC · October 14, 2016, 2:04pm

Sorry, I am trying to but having issues running UE4Editor atm.

Hey -

Were you able to reproduce this crash with Ctrl+Z? If so, can you provide any additional information on how you’re setting up the project as well as how you’re adding/moving the meshes?
