[Blue Burst] Desyncs after getting killed by SaintMillion several times, lost items on floor

[nolrinale]

Describe the bug
We were doing free exploration in the Undergroudn Desert for a while, got to the boss and we had left some redboxes and a few other items scattered at town floor, after dying many times and returning to town like 5 times or so the items dissapeared from my client but not from the 2nd player client he could still see them but couldn't pick up at all.

To reproduce
Fill in steps to reproduce the behavior, such as:

1. drop items on the town floor then with 2 or more players get to saintmillion
2. Die on purpose on the first or second phase with client 1, client 2 or both clients
3. Both of you return to town doesnt matter the order
4. reattempt to kill the boss again, die on purpose a few more times
5. items dropped at town begin to dissapear/desync
