BUG Vensim 8.1.0 crash nearly every model check

Just upgraded to 8.1.0, but the problem was occurring with the last version as well. Vensim quits with no error message when checking a model (cntl-t) or entering Synthesim, sometime in the "checking equations" process. The model is not trivial (attached) but not enormous. It seems to be able to withstand a check or a run immediately after opening, but if I edit an equation, save, and check again Vensim crashes most times.

It's the massive lookup tables you have in the model. The info they contain should really be in a data file.

The annual ones are probably fine; the ones with a step of .25 year are likely the problem.
Obviously this should not cause a crash, but it's not immediately clear whether the fix will support the largest tables.

Are you on Mac or Windows? I think I've got a fix for this (but it needs a little testing).
If you email us with your licence details, I'll give you access to the test version.

Thank you, I shrank those tables and it seems to work. I am on Windows 10 Pro. I will email the vensim at vensim one with lic info
