So it seems the chests and ammo are removed from my map when I do a memory calculation. I did not catch this previously and synced my changes which destroyed my project forcing me to place new chests in all locations because I did not want to lose all the other changes in that sync.
When I launch my session the chests do not appear in the first round, but on the second round of my 3 round battle royale they appear.
When I publish my map all of the chests appear in round 1 and the game seems fine…
But I have to remember to isolate my changes so that I can rollback after publishing so that the missing chests are not permanent. This is working for me as a workaround, but would love to get this resolved.
