V_Maiko, it was a string identification, your json file is missed maybe? Or in ERA 3 must be different way for it? Also there is no en version, and en json file, must it be the reason?

Cause on your screen there is the first string "Pandora box? do you want to open it" in rus file. There is no bug 100%. My English is pure. so i can't translate my mod

I will add a sound in next version of mod for new boxes, but old ones must have it, because mod do not rewrite them. I checked sounds and normal boxes have one of next sounds:
pickup01.82M;
pickup02.82M;
pickup03.82M;
pickup04.82M;
pickup05.82M;
pickup06.82M;
pickup07.82M
