SOLUTION
LBT 1.10 has been released and anyone using the LB Versioner from LBT 1.10 onward into the future will not experience this problem. So the recommendation for anyone who has this issue is just to install LBT 1.10 via the Food4Rhino installer or Pollination single-click installer. Then, you’ll never need to worry about the problem as long as…
A NOTE OF CAUTION
If you use the LB Versioner to go back to a version of LBT before LBT 1.10 (or, more specifically, LBT 1.9.48), you will have some broken functionality. This includes the LB Versioner, itself, not working well along with a dozen or so mildly broken Honeybee components.
IF YOU NEED TO GO BACK TO AN OLD LBT VERSION
To help those people who may need to go back to old versions of Ladybug Tools, I have updated all of the installers on Food4Rhino for LBT versions 1.6 through 1.9 such that these will all yield fully working versions of the plugin. Versions of LBT before 1.6 are unaffected by this bug. So sticking to the stable releases installed via Food4Rhino installers should allow people to use old versions of the plugin if they need it.
If people really, really need to walk between versions 1.6 - 1.9.48 of LBT via the LB Versioner, there is a way to fix things via command line after running the Versioner but I would rather not get too deep into it here since just reinstalling to a stable release is going to be much cleaner and less error-prone.
