EVA construction Claw Jr. bug

[Krazy0]

Describe the bug
The Claw Jr. sometimes has cyan texture bug and error text on screen after placing or moving with EVA construction. Once, a claw with the cyan bug also could not be removed again with EVA construction. I didn't notice problems moving any other parts so far.
 
Screenshots

Claw on the ship cannot be moved. This happened many game sessions ago.

The 2 on the ground were first removed from ship 1 inventory and placed on ship 1 without error. Then they were removed and placed on the ground and both became cyan and showed error on screen. Then they were both attached to ship 2 without error and the texture was fixed.

List of mods installed:

• Restock and Restock+ 1.5.1
