As of tellme-1.12.2-0.7.0-dev.20181108.025215 and tellme-1.12.2-0.7.0-dev.20181219.233102, it seems a lot of achievements causing NPE and dump a callstack in the logs:

On our large modpack, we've 672 such errors for 503 achievements actually dumped.
I suggest to throttle the callstack dump, only logging the first 10 per command run or something.

The advancement dump is pretty new and apparently not much tested... I guess I need to also add null checks to all the stuff in there.
