pretty much the title, though unsure if this is the cause.
i was whitelisting chest blocks to fluidlogged api so that they can be waterlogged
placed down some water on the framed chests from bibliocraft, then i moved back a bit and then i crashed about 10 seconds later
heres the crash report: https://pastebin.com/fP64M0Tb

This looks like the same issue as #84 and should be fixed in the next release.

Yep, same issue.

ah sorry about that, i did a search for the first line of the stacktrace but i got no results.
