• The expiration date is now recalculated if the relevant sandbox options are changed.
  
• Fixed error when plumbing objects in multiplayer.
  
• Fixed some occasional errors when receiving squares.
  
• Removed a debug print I forgot to remove from the previous update.
  
• Small performance improvements.

• Tainted water is now much more dangerous. Drinking it will make you sicker, and drinking it repeatedly can be fatal. Traits have a significant effect on this.
  
• Reduced potential stuttering while loading new chunks by spreading work over multiple ticks.
  
• Improved overall performance
  
• Maybe hopefully ideally fixed the filter recipe not showing up

Breaking changes have been made to most of the API - I don't know of any mods that use it but if you do sorry :(

• Removed Proportional Water Loss sandbox option. Water loss is always proportional now.
  
  • I couldn't really see any reason anybody would want to turn this off, but I'll re-add it if someone complains.
• Minimum remaining water in containers now scales by the size of the container. The sandbox option sets the value for sinks and other 20 capacity containers.
  
• Fixed a vanilla bug where washers/dryers don't synchronise their plumbed state immediately in multiplayer.
  
  • It's not really in the scope of this mod to be fixing random vanilla bugs, but I didn't want anyone thinking this mod was causing the issue.
• Some small performance improvements

Fixed difficulties plumbing sinks in multiplayer

Valid wrenches for adding filters now use the "PipeWrench" tag - this won't have any effect on normal users, but adds extendability
Fixed an error when right-clicking certain objects

Hopefully fix some context menu issues

Fixed rare error when plumbing
Removed global object patch, as they seem to have been fixed in 41.78
Misc code changes

Fixed metal drum behaviour

Features
Optionally, plumbed taps now need a filter added to them to purify water
Other
Fixed all major vanilla rain barrel bugs
Fixed saving to the wrong mod data key (lol)
Lower memory usage
Now modular, so should be easy to mod

Fixed taps staying tainted after being plumbed
Made improvements to ensure only taps are contaminated (although unsure if this was an issue)
Stopped redundant running of code on the client
