I Keep instantly dying when entering Fronos (Even in creative)

Minecraft version - 1.12.2

Mod version - 4.0.5

Potential cause (unsure): bad competability with techguns2 or other galacticraft addons (Compatability fixing mod is installed)

How to reproduse: I don't know. Sometimes it happens, sometimes it doesn't.

Sometimes it happens, sometimes it doesn't.

It is even harder to guess what's going on. Maybe any crash log or death message screenshots?

Death message was: "Player have fell out of the world" (As if I died in the void).

Crash logs: game doesn't crash on that planet so it's not gonna give any new info.

additional info: Instant death 100% right after landing. Can also happen if enter some specific places in the world.

As for mod compat: Not sure, needs more research. I suspect techguns only because it has biggest impact on performance, but I'm not sure of it.

I do also suspect that it's only happens in a specific save file. Gonna do more tests and report back here. Also gonna ask Techguns' dev about it.
