With module manager 2.6.25 (not sure if .24 did it), I am getting numerous exceptions in the log on loading:
Example:

could you send me the complete log please?
does this happen with mm 2.6.25 but not with 2.6.24 ?
also, what mods are you using SB with?

Attached, I think you can get the mod list from the log.

I'm happy to try it slimmed down, too, take a peek and let me know if you want to try to narrow it down to a specific planet pack.

KSP.log.txt

it looks like you have PluronKhato installed,
try the latest release it should solve this problem. (I have just released it)
if not, feel free to reopen the issue
