I crashed my heli and when I revived, I could not access my hotbar, either with my mouse or keyboard. I logged off and restarted my PC. When I signed back on I had died for some reason, but could still not access my hotbar, weapons, tools, etc. Also. my backpack is not at my place of death, even though it was only 10 -15 minutes between dying and returning to spot of death. Odd stuff!
