Pretty sure nobody saw it coming until after we had all completed the update with the event that triggers the lock since there were several updates between the update with the trigger, which was 0.6.0 I think, and the update with the lock, which was 0.9.0 part 1. There is no logical conclusion that a game dev won't block content in some way, in fact, it isn't uncommon at all to just not be able to 100% everything in one run. The only way to know if a dev will or will not block content in any way is for them to say so. In this case, we have known for some time, even had a bit of time to prepare, but we were told too late. This game is one of the outliers that allows 100% in one run, you just have to take active steps to avoid triggering locks to do it, which would be much easier if Selebus would tell us there will be an event in the update being announced that will lock content at least if not also telling us how long to avoid it to avoid the lock. He did do a good job telling us of the second lock, so make sure you have Sara's lust up, if I remember correctly, or there will be locked content sometime in the future.
