Overviewer 0.19.9 with Minecraft 1.18.2 world "IndexError: index 1 is out of bounds for axis 0 with size 1"

[sethborg]

This is a very old world from 2011 that has been updated to each patch throughout the years.

Error:

2022-10-01 12:38:23  Rendered 1958 of 2773.  70% complete.  ETA: 00h 00m 46s
ERROR:root:Could not render chunk 58,129 for some reason. This is likely a render primitive option error.
ERROR:root:Full error was:

IndexError: index 1 is out of bounds for axis 0 with size 1

Here's that block of code in world.py around line 1532 with the second to last line being line 1532:

        # Turn the BlockStates array into a 16x16x16 numpy matrix of shorts.
        blocks = numpy.empty((4096,), dtype=numpy.uint16)
        data = numpy.empty((4096,), dtype=numpy.uint8)
        block_states = longarray_unpacker(block_states_data, 4096, num_palette_entries)
        blocks[:] = translated_blocks[block_states]
        data[:] = translated_data[block_states]

Seems to be some issue reading the 1.18.2 blocks? Is there any way overviewer can be made to skip chunks with issues and keep rendering rather than hang?
