Same here the horse trick does work but then you end up fighting skinning the animal and remounting your horse which gets annoying. Hit the skin button and you remount. I also have had birds fly over and get irritated hundreds of times. Now I delay before I skin which does no good but I tried anyway.
The hide outs did not show up for me or my posse and we rode to every hideout location over a 6hr period normally they pop up many times during that time span.
Solution Found and thank everyone for your help. For future reference: Rockstar gave a gift awhile ago of 10 explosive slugs and I never used them so my recipe would not come up. I found this by accident. Knowing I had never made them before it threw me off. I shot a couple of rounds and I could then craft them. Again thanks.
Hit lvl 84 bought the pamphlet have slugs and fat it does not show up to be crafted best 950 i ever spent. It sucks now at the fence it shows as purchased guess those are gone forever. Maybe time to go to a new game.
