.. and the game freezing because of it. This issue is very weird as it only affects steam connections. It started occuring ~7th October 2025 out of nowhere and only affected some players. I tried changing the packets id, but that did not help with the issue. Adding random padding for whatever reason makes the packet go through. As far as I know this is the only packet affected by this phenomena. I suspect this may be caused by some upstream network config change? Some kind of firewall or filter? Whatever the cause, obscuring the packet works.

Most of the reports for this issues were on 1.5, but there was at least one case of this issue on 1.6. This change probably should also be applied to the 1.6 branch (dev)
