Savegame from 347957 -> 348553 will always crash now

Same issue here.

I think it has something to do with the Water Sieve processing a lot of Polluted Water at once (per pipe tile)

However, I've discovered that the Pipes aren't functioning correctly either; running in a direction it shouldn't

Additionally after I've rebuilt the Water Sieve it the game seems to work fine.

I've been having it too on my colonies. Load in, speed 3, unpause, crashes within ten seconds
