1.17.1 Client-side crash in Create when movable blocks move
Describe the Bug
When placing any contraption that results in movable blocks being rendered, if the client attempts to render these moving blocks, the client crashes. If on a server, the server does not crash, but the client will still crash when it sees the moving blocks in question or enters a world where movable blocks are moving.
Reproduction Steps
- Place a windmill bearing
- Add at least 8 sails(2 on each side) to a radial chassis with glue attached to the windmill bearing
- Activate the windmill bearing
- Client crashes instantly.
Expected Result
When contraptions with movable blocks operate, the client should not crash.
