Chest Teleporter Bug (NOT when dropping the item), some chests disappear

Had a run recently where I teleported the following chests from Chamber 3, in the order shown:

Blue (locked)
Green (locked)
Brown (unlocked)
Red (locked)

Upon entering Chamber 4, there were no chests in the entrance elevator. The boss foyer had the following chests in it:

Green (locked)
Red (locked)
Blue (unlocked)

Seems as though the last chest I teleported (the Red chest) did not appear in the boss foyer. Perhaps the game is not spawning the chest because it would take up too much space in the foyer room. Either way, I ended up missing out on a Red chest from Chamber 3, that could have spawned as a Black chest on Chamber 4.

This explains why I always seem to find Chest Teleporter to be worse than it actually is: By getting "lucky" and upgrading a bunch of chests, some chests will refuse to spawn in the boss foyer.

I did another test with Mod the Gungeon. After teleporting 20 Blue Chests and 5 Red Chests, only 9 chests appeared on the next floor. 8 were Blue in the entrance room, and 1 was green in the boss foyer room.

Hey, is that true the teleported chests drop exclusively guns?
