tell me what addons and ill test it with my friends and see if i can find out which one. sometimes its a networking issue though
it only has happened once while playing on bedrocks "lan" feature so basically multiplayer
i have had this issue too but mine was a world save corruption issue. it corrupts upon saving or loading and it is quite annoying so backup your save often as a temp fix
if you have addons in the world or have trusted skins off it will not work. it also has to be a png
and its windows 10 edition. its in the environment list
