Maybe there’re even several issues at play here. Today, after some attempts with a new build, everything spawned double or even more:
With a grandiose 3 to 17 FPS, it was difficult to even see what was going on there, but there you have it, thanks to cloak mode.
Never had that on the beta client btw.
P. S.: I found at least on more Commander in the castle, so at least a triple-spawn.
