Your Expectation

Adv solar boiler do not explode after logging in.

The Reality

up on loggin in after several hours and a server restart my adv solar boilers exploded from adding water while hot (expected).
how ever all the machines, water tank and solar boilers, are in one chuunk that is not loaded (forced or via anchor) or has a loaded chunk next to it.

The boiler are attachted to the water tanks with no pipes in between them. See screenshots

From some testing with the server owner we saw a massive water drain on the tank when logging in. This tells that the boilers are or nearly empty of water (not expected). The rain tank can produce enough water to keep the boilers going forever.

If need be there is a save file available for review.

Speculation

We susprect that the boilers may be ticking while the water tanks do not/dont push water.

What happened:

• Logged in, boilers blew up moments later
• Server operator stopped server and restored region file to overnight backup
• Server started, and the boilers were rapidly filling up like they were empty
• Server restarted, boilers stayed full
• Server restored again, boilers were empty

Tank and 3 advanced solar boilers all in the same chunk. Outputs set to pipe correctly. Tank is directly adjacent to 3 boilers. Running fine normally.
Not chunk loaded. SU chunk load of 1 chunk 3 chunks away without shared piping. This chunk should be idle.

My suspicion is that for some reason the ASB keeps ticking when it should not, and the RC tank doesn't tick and so it runs out of water.
