Summary	0003050: Actor health above 32767 is incorrectly transmitted to clients and causes weapon sprite desync for players
Description	Actor healths are apparently transmitted to clients as 16-bit signed integers, just like tids and inventory item counts were in 2.1.2. Setting it to a value above 32767 may cause clients to think it's negative and desync weapon sprite while keeping the game playable. This bug happens in both 2.1.2 and 3.0
Steps To Reproduce	1) load the attached wad which sets player health to 100000 2) note that the client thinks health is negative and breaks weapon sprite
