Whenever I go on any other planet then mars (and the moon) I keep on getting damaged even if I have the thermal padding armor on...

And when I die it says : CedTec forgot his thermal protection ! (something in those lines)

Modpack version?

1.5.7 and also 1.5.8
But really... I've seen other people do it... have I missed something ?

What do you mean?
Are you wearing a thermal armor?

Same issue as this, seems like
4Space/4Space#37

Yes... wearing full thermal padding...

I dunno what the issue is... works on mars and the moon, but fails for all the other planets

Hm, are you sure you have the issue on 1.5.8? As I fixed that issue in: 82f1af9

What version of 4Space do you have in your folder and what launcher are you using?

thx for this custom version, it solved my problem with getting damage for now
for me, i used 4Space-4.1.9 before and it did not work with that version.
