This remains an issue and i cannot for the life of me fathom why. Make it so that a player has a 3 second cooldown between each time they drop supplies, not even the lowest latency server would be effected then. You dont even have to fix the underlying issue just make it impossible to drop supplies without waiting a few seconds inbetween and this exploit will be fixed.

Worth having a look at your gpu drivers, the game started crashing on me every like 15 minutes recently, turns out the drivers werent downloading automatically anymore.

I continued to encounter this issue when I tested the same spot with the new experimental build version 1.2.1.76 on an official game master eden lobby [13481319 (US-LA)]

This continues to be an issue on version 1.2.0.124
I tested both the soviet and US heavy machinegun nests earlier on an official game master lobby
Im not sure if there is a more up to date version but the current version on official lobbies still suffers from this issue

This is a constant issue on every game I play on official servers. I also have a suspicion that the reason so many games crash so often is directly related to this, whether it be because the server freaks out directly due to this glitch or if the abundance of supplies allows people to make far more vehicles and AI than they would otherwise be able to, putting strain on the servers that would be almost impossible if supplies were being generated and transported the way that is intended and not easily replicated at will.
