Creative Bug

Hi there, ive recently published a map, and I keep losing players because of 2 bugs. the first- after every round second and third player gets eliminated and its forced to go lobby automatically and join back in.
and the second- after second round whenever the players collect the weapons, the slots get smaller and they cant use the weapons until they mantle a structure.

Please support me solving it.
thank you,
