With no apparent reason, sometimes my irrigation water will back up on a particular hydroponics tile, even if I disable it, rebuild it, rebuild the pipe, or leave it without a plant. The pipe blueprint seems to be the only solution that works, and this one tile out of all the hydro tiles is the only one that does this.
I can't for the life of me understand why this is happening, and I can't imagine this being anything other than some sort of bug.
If I'm just being dumb or missing something, please let me know.
Build long stretches of hydro farm tiles as shown, past that I do not know.
