Game mode: Singleplayer
Game type: PvE
TestLive client: 3.0 update, Revision #398570/34354
Detailed information of the occurrence:
Testing the new building methods with admin permissions while in creative mode. I used the usual stairs/ceiling method in order to place a pillar on the cross section of 4 ceiling pieces, so that pillars line up on the side of a wall.
When attempting to replace said stable pillar with a Nemedian pillar, the game crashes to desktop.
Replacing the pillar without having the inverted wall piece also causes crash. Can reproduce in the same location, but in the opposite side the pillar replaced with no issues. Unsure of the cause as most of the time and on the live server this process does not have any issues.
