I did experience crash by Stop the ped. Which I was cuffing the same guy with my backup units. The game freeze and crashed. But all in all it's a cool experience in LSPDFR though.
Sure, lspdfr is unstable, but it can run correctly not all the time but at least like half an hour. If you play a big open world game for hours or days, it's acceptable that you experience bugs or crashes. You can't just make an impossible request which you have no bugs or glitches in a big open world game with high graphics, high fps with days running time. Also, LSPDFR wasn't really a game, just a mod having different setting(I think it will be better to say it violates) with the own game. Few crashes, bugs (Maybe crashes each one and a half hour with 10 plugins) is acceptable for me. And I think you can make a support forum if you find unable to fix the lspdfr problem. Because it might not be the problem of LSPDFR. Might be just your antivirus delete some file and making it not working.
