1. Minecraft version: 1.12.2-forge1.12.2-14.23.5.2768
2. Galacticraft version: 4.0.2.190
3. GalaxySpace version: 2.0.1 STABLE (2.0.7)
4. AsmodeusCore version (for 2.0.1 version and above): 0.0.3 (0.0.7)
5. Side (Single player (SSP), Multiplayer (SMP), or SSP opened to LAN (LAN)): SpongeForge(b2768), also tested in SSP

Description of the issue:
Launch controller won't work with advanced(5x5) pad. T6 rocket lose sublight capability when hand/weapon broken for placement elsewhere. Hand broken sublight capable rocket can no longer edit sublight capability in modification table(remove/reinstall would be easy workaround, cannot even add anew) Duplicate rocket in lander when sublight capability not broken. Duplicate rocket retains sublight capability..rocket w/o sublight and pad in typical slots(lander)

Prior release(2.0.6) had issue(crash server on chunk load) with oxygen storage cluster, haven't tested again w latest. Happy to see blaze boss fixed..will retest that soon as well.

Screenshot/Video:

Attached log file (or url on pastebin.com):

"Advanced Oxygen Module" rather..fails chunk. Didn't actually reboot to see if it crashed server as previously experienced, my guess is that it would as it simply wouldn't load the chunk until I /setblock replaced it w air.
