When a large resources is distributed among several chunks, the displayed quantity of the resources may differ from the actual amount. For example, geothermal water is simultaneously distributed between two adjacent chunks. The actual reserve of geothermal water is only 200M, but the monitor will show it as 400M. If there are four chunks in distribution, it will be displayed as 800M.

i played with py mod,This mod contains a large resources, and it is very easy to trigger this bug.

@moFFsto thanks for that report! I haven't checked Py compatibility in a while, but I though I had finally squashed all those Py-specific bugs. It'll take a while for me to get into that. All I can say right now is that in the past, most of these Py-related bugs came from Py doing some scripted stuff that is impossible to detect in a general way.
