You can do it by trying to save the botchling maybe? You should have some autosaves from a bit further back.
Do some sidequests, but make sure you do main quests before you become overlevelled (5+ levels over recommended quest level) otherwise you get literally 2 xp
Haven't willingly changed horses though, Iwas thinking it might be the one I had to ride in 'The whispering hillock', but checked and it's an actual bug.

Yeah it's not La Paz or Cusco, but the difference between Lima and Bogota is very noticeable when trying to play football, not sure where Huracan are from but if it's an altitude similar to Lima then it's definitely going to affect them.
EDIT: Just checked and Buenos Aires is 34m compared to...
Yeah no decision is going to stop you finishing the game, but they do have some 'weight' behind them (good example is 'the whispering hillock' quest). Truthfully there aren't any genuine 'incorrect' decisions, just that the decision I made had consequences that I didn't want.
Bit late on this, but i played some football in Bogota when I was there and I was dead after like 5 mins. It's high enough to make a big difference unless you've had some time to train/adjust
Did the 'Woodland Spirit' witcher contract for the first time last night (trying to get them last few trophies),
Even in a sidequest like that there were some hard decisions, and i think I chose wrong.
Even the worst parts of W3 are only comparatively bad in comparison to the rest of the game (Dandelion stuff IMO)
Still got a few bugs though, for example my Roach is now black
