I think the way Limbo works is similar to Floodingthe locations effect doesnt start until it starts a turn that way. A not-uncommon scenario is as follows

-turn 3 Storm turns a location into Flooding. One of the other locations is Mirror Dimension.
-turn 4 that Storm location is Flooding. Mirror Dimension turns into Flooding. Storms location turns into Flooded at the end of turn.
-turn 5 the second Flooding remains open and becomes Flooded at end of turn.

The first time you come across this, you might expect that the second one would also become fully Flooded at the same time as the first, but it doesnt.

I would assume a Scarlet Witch on turn 6 changing a location to Limbo would also have no effect. Does a Scarlet Witch turning a location to TVA on turn 4 end the game? Id bet that also doesnt work, since you wouldnt get the Times Up animation at the start of the turn.
