Softlock when ending level in Lake of Fire

[trigger-segfault]

Describe the issue
When ending Lake of Fire from the pause menu, the game speed did not reset from 0% to 100%, and the level had no way to finish the teleportation sequence to skip to the rewards menu.

Expected behaviour
Units should have started teleporting up, and game speed should have reset to 100% speed.

Steps to reproduce
I have not yet been able to reproduce this, but I was researching construction erosion for about 10 minutes on this level with game speed set to 300% and then 0% before ending the level. There were at least 20 construction zones placed, most with barriers, and some with lava eroding solid or path tiles. Some construction zones were cancelled. There were around 25+ rock raiders in the level.
