0184.2: Base doesn't respond gracefully to grinding down interior hallways

[daring raft]

Bug name: Base doesn't respond gracefully to grinding down interior hallways
Priority: Medium
Game Version: 0184.2
Description: I've been able to repeatedly get the game to respond poorly when the player deliberately grinds down interior hallways in a large base. All oxygen in the base will be vented (even in parts of the base protected by double airlocks), and two out of three times I did it, all water was drained from an exterior tank and the water system collapsed with a NaN error (see screenshot). Fortunately, the water system recovers from the NaN condition when the player does a save and reload, but the lost water and oxygen are permanently lost.
Reproduction steps: Build a fair size base. Start messing with it in totally unfair ways. Watch the game respond in ungraceful ways. I've attached a save file to play with immediately after inducing both oxygen collapse and a NaN water system collapse.
PC specification: N/A
[Optional]: Screenshots/Short film: Below

(Note "NaN" under Supplied water.)

I get this when I started a new base after the update, then when everything was fine I grind down one airlock I get NaN nightmare return

This occured for me grinding down a dome. All interior stored water in the base vanished as did water in my external tank. The only water not drained looked like water stored in wells. It seems that grinding down any part of a base drains all the water.

It didn't happen beta version so why did they change it! If they added a tap on the large water & oxygen tanks we could turn if off rebuild the base and turn it back on.

I think it may be more an issue of the 'network' structure of the connected modules, than if there is water flowing so not sure an on/off valve would help

I'm having this same problem, need to check if it fixes with save, but lost all water throughout the whole base

The workaround is to disconnect all of your external tanks from your base before you start grinding parts of it. Finish reconfiguring, get it looking like what you want it to look like. Then save, then immediately reload that save. After that, it will be safe to reconnect your water.

It apparently occurs when grinding down ANY module that has the capability of transporting water. I ground down an outside airlock and had the NAN error.

Yep.
