I was playing earlier today, and a teammate killed me. We kept having to wait for our inventories to restore, I waited about a minute and my inventory never came back. I picked up some bullets, and I think that probably would've cemented it. My inventory is also reset on my profile page. I used to have sg ssg mg cg and some grenades...
As you can see, a lot of it's gone. The cg and the ssg I picked up after my inventory didn't restore.

I'm sorry for this problem.
I have identified a bug concerning the inventory and it's already corrected for next version (save it before read it just after respawn).
But most of inventory problem come from the actual charge of the worldserver. I must optimize access to the database, else some request lock others ... the webchat also consume a lot of database access, need to be separated and optimized.
