Game freezes after clicking "Save and quit to title"

Happens most of the time, I'd esimate about 80% of the time. Tested on 4 completely different laptops, all WITH and WITHOUT mods (MCForge 1.10.2-12.18.1.2011, BetterPvP 1.9.9, XaerosWorldMap b1.1.1, Optifine 1.10.2_HD_U_C2) and still got the same result.
