UPDATE: GSC deny the report on their twitter here.
ORIGINAL: According to this report from Ukrainian news site UkraNews, GSC has been shut down by owner Sergei Grigorovich. The closure was apparently announced to the workforce earlier today. The autotranslation is messy, so if anyone can explain the sixth paragraph – which tries to speculate on what was going on – accurately, that would be great. I’m going to see if I can get in touch with someone from GSC.
