Sidenote: ELS v6 seems to be the main culprit for crashes, and Lt.Caine is impossible to get hold of, so I would suggest ELSv5 as it's much more stable, and you don't lose many features.
1. When I respond to any shooting calls, the second I get there all I find are weapons on the ground and it says the call is complete.
2. My character becomes completely invisible after handcuffing suspects on occaision.
3. Once you pat down a suspect they walk off and you're unable to arrest them.
4. After a while (around 15 minutes) of playtime I stop recieving callouts, even if I have them enabled. Toggling doesn't solve it, neither does re-loading my GTA:IV save.
5. If you call a transport, they abandon their vehicle and walk the suspect to the nearest police station.
Other than those, excellent mod!
*edit: It also doesn't seem to be compatible with my ASI loader as it doesn't detect it, but the mod runs fine apart from the above. Can someone point me in the direction of a compatible one?
