This mod causes lag when building once your factory is "too big".
Everytime you build ANYTHING the updatetime for the your mod increases.
You can see this if you show the "entitiy-update-time" in debug options.
When i built big outposts with my personal roboport the game dropped to about 20ups.
uninstalling your mod, but keeping just the Stone Water Well mod on itself fixed the issue for me.

Absolutely no Idea whats going on here.

I still have a backup of my Safefile with your mod installed if you need further information.
Id be more that happy to provide videos, logs and screenshots if you need any!!

I think I've fixed it bye moving the check for the entity earlier.
I first used the same ordering for the checks as space exploration+K2 but it seems remote interfaces are really slow (i guess this is it since it really is the only thing that could be slowing it down.)
Can you please install the latest version and check if its fixed?
Thanks in advance.

Thanks for the hyper fast update. Will check right away!

Yeah, the lag is gone! Thanks man!
