Describe the Bug

When the mechanical piston starts extending/retracting, the extending head and the blocks it's pushing disappears, and reappears when the mechanical piston stops.

Blocks above the cart assembler also disappear when it's on the minecart.

Reproduction Steps

1. Build the newest source file
2. run it in a server
3. build whatever with a mechanical piston and/or a cart assembler
4. activate the build.
   ...

Expected Result

blocks become invisible

This should be fixed with the latest build. Please test it and let us know.

this is an issue with packets I introduced in here, should be fixed soon. Use an earlier build for now.

Unfortunately no. In fact, the new build introduces a bunch of lag into it as well. The last build just disappear, then reappear, while this one lags, then disappears, then reappears once it's done.

should I include a video?

I cannot reproduce this with the latest build. Please do send a video in addition to a log.

File is too big for Github so instead I uploaded it to youtube as unlisted:

And then it spams the same errors for 3 minutes straight,
So error is client side.

Client computer config (i doubt this helps but it might):
Intel Core i7-10710U
16GB DDR4 Unknown Frequency
512GB Samsung SSD
Intel UHD Integrated Graphics

Server computer config:
Intel Xeon E5-2620 v3
8GB DDR4 1866MHz

It works now. Sorry for wasting your time lol, might be me mixing up different source files.
