No offence intended - the game is different here.
Most rules apply, some do not, and there are limitations to a few rules. A major one is "no player choices" which means no unplayable, no deliberate drops.
The other one is, OOB balls are gone for good (think of undue delay), and there are more OOBs than on the real courses. Here, the mini maps give good but not unfailable hints to the limits. Me thinks that these extras are there because they didn't shoot photos from these places - all the left sides of STA are clear indications.
So, don't worry about it but take it like a man ;)
I see ball wear and lost balls as the entry fee to the game. Luckily, we're free to decide how much to pay so we may downgrade if a lost ball hurts too much.
Have fun!!
