>What did you do?
placed a pipe a couple hours ago with a heatpipe with heat source attached so it wont frezze

>What happened?
pipe froze
It had too work at some point because the em plant attached too it has done like 12k products

>What did you expect to happen instead? It might be obvious to you, but do it anyway!
Pipe should not frezze when heatpipe is ~300 degrees

>Does it happen always, once, or sometimes?
happend once
i did replace my name in the logfiles with [user] before upload

Thanks for the report. Do you remember what was happening around this pipe? Can you reproduce this issue or was that a one-time event?

What do you mean by what was happening around the pipe?
I set it up when i first came too aquillo and didnt changed anything since then until i came back and noticed this if thats what you meant

I only have seen this happen once for now

Well, there is not much i can do with this if i do not know how to reproduce the issue. You can fix this save file simply by removing and rebuilding the pipe.

I did some small amount of experiments with this and the pipe is definitely recognized by the heat pipes because when heat pipes cool down and then reheat then pipe is unfrozen so the heater connections are setup.

ok thank you

is there anything i could do too help you solve this when i encounter this problem again?

If you could reproduce this, the interesting part for me would be the order of entities being built, if it was pipe first or heat-pipe first, if they were built from blueprint, manually or by super-force building, when the heat-pipes started warming up, anything that would help recreate this issue from a known good state. This issue looks to be more like a single bit flip and given this is the first report about this in a feature that basically every player on aquilo depends on i am more likely to blame hardware than a logic error, so since this was a one-time event it makes me more suspicous about bit flip rather than game bug. Only reproduction can prove me wrong and i cannot do that from the provided details.
