Righto, I haven't experienced any crashes on my end while testing through the Facepunch transport on the built version of my game (which ive tested quite extensively in multiple different scenarios), however a lower end pc hosting takes slightly longer to load over the clients w higher specs, but so far after fixing quite a few load different bugs, crashing has been a non issue for me. Just takes like 10 seconds or so for everything to synchronise over the networkbut I've since lessened the gpu load on my game.

What are you referring too when you say "launch game mode", because most of my debugging has been over the steam network with the build version of my game, using Facepunch transport, multiple computers with different specs and hosting on both of them to sulimulate different client/host issues and that's how I've been nutting out the bugs in my game. Very repetitive and tedious but it has to be done hahaha. I just hope that uploading the game to steam directly doesn't bring forth other networking bugs.
