Expected behavior

Fawe use for regeneration of chunks some methods. Normally getBlockEntity gives us every block tile entity from the chunk.

Observed/Actual behavior

The chunk level data random empty.

Steps/models to reproduce

  1. Clone https://github.com/IntellectualSites/FastAsyncWorldEdit/pull/2171 branch from me.
  2. Clear a section with FAWE and try to regenerate the cleared area.
