1.0.1: /tpx -20 fails with crash

[Sen-Mithrarin]

Version:
1.0.1

What is the bug:
I don't know what level -20 belongs to but it keeps crashing with this error :

Seems to be an error with Railcraft.

Mod & Version:
maybe Railcraft

Can it be repeated:
Yes, client keeps crashing even after relaunching with command /tpx -20.

Known Fix:
none

Why are you trying to teleport to dimension -20 if you don't know what it is?

 

[Sen-Mithrarin]

Well ...
- because it is there
- because /tpx give me the power to go there
- because there is no information what DIM are used by wich mods
- because I can't find any DIM in the configs because it's hardcoded into the mod
- because even Google can't tell me wich mod it does belong to so i can try go there "the correct way"
- and of course : because I want to explore ...

So I found out that -15 belongs to "The Deep Dark", -17 and -19 are "The Twilight Forest" ... and -47 is really strange as it only contains endless bedrock and a few top and bottom layer of sand (and is somehow bugged as the physics don't apply correctly to the bottom-layer sand).

In fact : it's just the same as many mods : no documentation at all. I don't really want to check every single mod that is in this pack just to find out wich DIM belongs to wich mod so I can figure out a way to enter the DIM correctly. This information should be provided anyway along this pack.

Ok, there are lots of well documented mods out there. But most still lack some informations as for example AE2 does. It uses a separate DIM for its "Spatial Storage" but it's no-where documented wich. So maybe DIM -20 is the AE2 Spatial Storage, may not. I just don't know so I'm just unable to solve it out by myself and therefor I need help of someone who knows about this extra DIM and can explain it to me.

Spoiler: BTW

your post was really useless as it doesn't matter why I want to go there or how ... this was a report that there is a bug that keeps occuring even after done "the standard methods of trail and error" and without any information to solve it
in fact : only the exception makes me think that it might could be to do something with railcraft ... but of course I could be completely wrong on this
