this seems to be a server side issue as single player works perfect with more than 1 camera view. here is the error log:

if there are any other log files you need let me know.

Thermos build 58 has fixed compatability with LookingGlass.

If it works, then OK. :D

Please use pastebin or text file uploads for future logs. Copy-pasting the log here makes it hard to read and takes up a lot of space.

If you are still experiencing this issue I'd like to have a log file of the occurrence. :)

I have actually moved onto using Thermos 1.7.10-1614, however it has a different issue with lookingglass.
The other open issue is here: CyberdyneCC/Thermos#400
