Reported a few times by friends, but then it also happened for me. When creating garrisons and OPs as SL, the spawn point is invisible to the SL as well as on the map. When I died, I did eventually get to see the spawn points and spawn on them. This happened on not just Slomensk but also Driel.
I also recall my SL at the time on the Driel game saying the commander couldn't use any abilities at the same time the spawn placement bug was happening. Not sure if linked.
