[Bug] Catalyst cannot be placed in Reciever and Transmitter

[RedstoneGyerek]

Describe the bug
When I tried placing Gilded Blackstone into a Reciever and Transmitter, the block appeared for a tick, played the placing sound then disappeared. It was inside the the R and T, I could right click again to take them out, but the blocks wouldn't render it inside them. When I broke them, they didn't drop the Blackstone.

To Reproduce
Steps to reproduce the behavior:

1. Right click with Gilded Blackstone
2. Nothing meaningful happens

Expected behavior
Should visually appear in the Reciever and Transmitter, and they should start functioning.

I tried modifying the frequency in a Radiosmithing Station, with no luck.

Here's the data of the Reciever:

I also encountered this issue.

When it happens, none of the usual information is shown (frequency and modulation, antenna power).

It needs more testing, but sometimes the item renders and the associated information display correctly.

It might be worth noting this bug only seems to appears on dedicated server.
