Good. The other errors I'm seeing are this:
2021-12-27T09:29:06 2700.419 WRN No chunk for position 1504, 43, 2044, can not add childs to pos 1503, 43, 2043! Block semiFlatbedFront

There are several instances of different blocks with this error. Hopefully someone else will chime in as to whether these are A20 blocks or A19 and if A20, if it means the save has some corruption due to your repeated crashes.
