OOS on rejoins have been fixed:
- Reported in #3107, fixed by r16857. Mirages were not updated after placing a foundation into the fog of war.
- Reported in #3271, fixed by r17223. Placing a foundation while having any unit discover a mirage at the same turn caused different entity ID order.
- Since alpha 19 has been released, I never encountered any OOS.
Mirages and foundations work properly, just not as proposed by the design decision sanderd17 is refering. Making uncommitted foundations local entities sounds appealing, could solve that still existing building-preview-cheat, would stop towers from destroying uncommited foundations and prevent enemies from seeing CCs before the workers have arrived.
The user should be able to place foundations into the fog-of-war, in particular for placing CCs.
Don't know why this ticket has the pathfinding keyword.
