Player->showPlayer() assumes that spawnTo() will take care of all the checks necessary to ensure we don't actually spawn a player to someone it shouldn't be able to see. In PM3, there's nothing we can do about that.
This could be a problem if anything decides to override spawnTo() to do additional stuff and assumes that the function will always succeed; however, there's not much reason to do that (plugins sending packets should override sendSpawnPacket() instead).
this should never be hit in the PM case, but it's an InvalidArgument rather than AssumptionFailedError because plugins can and do call this with bad things.
setGenerated/setPopulated and friends set hasChanged = true, which causes the world to autosave them the first time around, even though they weren't modified.
PHPStan failed on 7.4 after updating to 0.12.99, and I figured it was less hassle to just do this than fix the build. In any case, we stopped shipping 7.4 months ago, and warned at 3.22 release that 7.4 support would soon be dropped.
this was originally worked around by 47f7af6739. However, that commit was just duct tape, and I never bothered to investigate if the config was being checked somewhere else.
Here's to a years-old bug finally getting fixed.
while annoying, PHPStan is right to complain about this, because putBool() is impure, meaning that these fields could have been mutated in the call.
We know they didn't, but PHPStan doesn't, and we can't mark the method as pure because .. well .. it isn't.
