NullPointerException on BiConsumer.accept(Object, Object)
Closed this issue · 1 comments
So recently my server hit its disk space capacity limit, so I extended the partition size but after booting up the server again it seems about a dozen or so out of the 509 total imageframes gave exceptions in the console. The exceptions all looked identical to eachother. here is one.

After going through each exception and deleting each plugins/imageframe/data/ folder that generated an exception, the only exception left were about 2 of the following that were files located in world/data/map_.dat
