There is a statement on the Oovee Game Studios website addressing conjecture on reddit and their forums that rashes of game crashes in Spintires are the result of "time bombs" deliberately inserted into the code of the off-road racing game by developer Pavel Zagrebelnyy. The speculation was that the programmer was disgruntled, as he recently told Eurogamer that the publisher owes him "a s***load of money according to our contract," and that he hadn't "had a meaningful communication with Oovee for many months (maybe a year)." Oovee discredits these theories and takes offense at the speculation, and say that the problems have been identified, and fixes are in the works. That all makes this seem like a normal bug, but it does seem odd that the game is no longer for sale on Steam for the moment (thanks PC Invasion), which is not addressed by the publisher in their update. Gamasutra has a statement from Zagrebelnyy, who also says this was not deliberate sabotage, but rather a bug related to a date-related piracy check, and he says a patch should come through on Steam "soon," and in regards to Oovee, he "will try to pick better partners next time."
