Bug: BaseBlock NullpointerException

[Shibva]

Describe the bug
when copying a Stargate base block of any kind, the game will crash with a lang.NullpointerException

To Reproduce
Steps to reproduce the behavior:

1. place the Stargate base block in creative
2. use select block while holding ctrl (default keybinds CTRL+MIddleClick); this will cause the block with stored NBT to be added to the players inventory
   Expected behavior
   The game to not crash; lel

Mod version
4.11.2.4

Additional context
this issue is the same plaguing #290 and #291 so fixing this issue will fix those by proxy.
I talked with a few people about it and with their collective efforts, I managed to get some key information on this bug. It is the following:

• It's caused when the client attempts to read blockdata; the client and servers methods of getting NBT are different, the client method is the only one that's causing a NPE, while the server's is acting fine
• the erroring line was added in 8856f5e (found by using Blame) [at this point, the erroring line in this segment of the crash reports stacktrace would be at line 1804
• It's not caused by another mod; Crash Report was generated in a pure (JSG only) environment and was triggered using an in-game feature [block picking with NBT data save; ctrl+middleClick by default keybinds]
• It's not really a serialization error, this may or may not be true but I asked a developer friend of mine to take a look at this they said something about the hashmap that's associated with gatePosMap returning as null sometimes (probably because the location is not cached; idk)

Crash Report (Just JSG):
crash-2023-11-12_01.20.05-client.txt

My whole JSG config (as .zip)
Generated Config (Default) was used

why am I reposting this?
because it's over a silly little bug and after talking about It I decided to attempt to have this bug patched by gathering as much info on it as possible to put a stake through its bugged heart. This is an high-effort Stargate mod and I can see that, and for such I wish to help keep it like that by providing as much detail as I can to increase the odds of it being fixed

Anything else?
just this

Hope all of this helps and thanks for taking the time to read this ^w^
