Expected Behavior

Built a 9x3x9 structure with the required hatches and buses to form the fishing pond multiblock.

Current Behavior

The controller gives an incomplete structure error. A few things I tried, looking at the attached pictures:

• moved the controller on another side of the multiblock (right side), the blocks on the edge of the multiblock formed but not the ones on the inner casing, it still gives an incomplete structure.
• moved the controller on another side of the multiblock (right side) and all other blocks on an edge, all blocks formed but still incomplete structure.

Steps to Reproduce (for bugs)

Reproducible on GTNH v. 2.0.4.8 while trying to build the fishing pond.
Tried on an old save on GTNH v. 2.0.4.6 and the bug is absent.

Structure code for Zhuhai hasn't changed since before April, so the bug definitely exists in the older versions as far back as it's been in GTNH. The difference will be which direction you're facing, as it may form NS but not EW. Please move any further findings to the original issue.
