Something very strange is happening in my sever since 1.12.2 and is an ongoing issue in the latest snapshots too. I created a team on my SMP sever which consisted of my friends and some mobs. The idea was that this is the only reason i opped myself to do commands and then after setting our team i would deop myself and from that point on it would be classic survival gameplay- no commands etc. however when i logged on later i had to once again op myself and redo the /team command as the mobs on my team had gone hostile- in fact the game has appeared to have forgotten that i set up a team and only had me in the team and nobody else- so basically the team automatically emptied when i left. in 1.12.2 the issue was even worse as when i ventured further away from my team, the game slowly forgot they belonged on my team- so i returned to my base only to have to redo the old /scoreboard teams join command- this also occurred when after coming back from the nether. PLEASE solve + examine the issue please.
To recreate:
-set up a team that consists of yourself and one or more mobs, best use neutral/hostile.
-IF IN 1.12.2 walk over 100 blocks or more from said teamed mobs or go to the nether (or end) and come back.
-Or just log off and shut down the server fro some time.
-Upon return these mobs will no longer be on the team and will be hostile once more.

so yh, basically that is it- both my friend and the blaze get chucked off the team when i log off. When i log back on the blaze goes ablaze and starts incinerating things. I tried to get help off the internet, there literally is not a single word mentioned about this happening to anybody, so i gathered up my courage to come here. I DO CARE about this issue btw, i just don't know how to vote for it. This is the first time i ever had the guts to report a bug. I also wanted to add i never tried this with other mobs as i only have one server. This just happens to us three, and it seems to be only me to be the first one ever to have that issue. Also if i had not detailed anything fully, I apologize as i never done this before so yeah.

Thank you for your report!
