Hello me and a few of my friends have been playing the 1.7.10 pack for a little over 2 weeks now. Recently occasionally the server would get some big lag spikes and in the console there would be a ton of errors going through. One of them says [Backpack] couldn’t load data at all. This escalated to happening every time on of my friends was online. When he left it stoped. We think it was because at the beginning of the server he tried to put a backpack on his back but it would go on and just disappeared. We have already tried killing him and deleting in player file on the server, neither had any effect. If you know any thing about this problem please let me know if you were able to fix it and how to do it. Thanks.
