Describe the bug
Download version 10 (I have patreon subscription), mobile version. Make a new simulation, water, oxygen. Any simulation with only water or only oxygen works, but simulation with a mixture brings up error:
Error in '1': Object reference not set to an instance of an object. (NestedLoops.vb, 189).
I have v9.5, and everything works perfectly.
I have tried v10 on different computer, and it works perfectly.
I think there is some issue with my Windows setup causing this problem. Is it that I can only have one version per person per licence?
To Reproduce
PLEASE ATTACH THE ZIPPED FLOWSHEET FILE and/or inform the steps to reproduce the behavior:
