at first - sorry for non-english screenshots.
I have pressure plate in my "cooling room" for my glass forge. When liquid glass falls into cooling water, change state from liquid to solid, but pressure plate doesn't not register this weight. In screenshot.72.jpg - you can see pressure plate what shows only 10kg, but here is 175kg of solid glass (SKLO = glass)...
Tested with iron volcano - same problem.
When liquid material change state on pressure plate, this plate ignore this weight. After save & reload, this weight is registered normally (screenshot.73.png).
Game version: AP-399948-D
Steps to Reproduce
Create small room filled with water (or other coolant) with pressure plate in bottom. Let liquid glass or metall fall on pressure plate and change state into solid here...
