Script which is run to open up locked zones actually locks you out

I understand there's a script run early every morning with the aim to unlock zones that have previously been locked.
However, if you're logged in at that very moment, your island will now indeed become locked for the next 24 hours.
It happened twice to another member in my guild, and this morning it happened to me.

With explorers being sent out roughly every 3-6 hours and with Zombie Crypts appearing every 6 hours, don't even think about logging in and taking care of them in the wee hours (between 3 and 4 am GMT). Thanks to this, I guess I'm now losing a full day of collecting pumpkins.

For players in Australia end New Zealand this must be even more devastating...

This sort of makes sense to an issue I'm having this morning.

How can this happen though when people play from around the world? (or are just people who don't sleep :D)

Starting around 2100 local time the game locks out until around midnight, it is very frustrating. Based on reports I am hearing this is also the timeframe where generals are going to a blackhole.
