Today we gone to vMol and on the twins out of 7 times at least 6 times at the first colour change instead of 3-3 people, 3 and 6 people changed it colour. It was not a visual bug, since we did not exploded each other.
Damn, the twins are hard enough for some people when the colors do work...
*cries in the corner at the number of times a person who "has run it a million times" doesn't understand the mechanic*
