Someone correct me if I'm wrong but doesn't this:
" 5. All maps updated to map version 5.
As far as I can tell, the only difference is that map version 5 removed the following lines from Star and Planet definitions. Probably because they weren't that popular, and their default values in galaxy forge weren't that accurate.
However, the change log says there is backwards compatibility with map version 4. So if you do really use these lines in special maps, you can continue to use them and ignore this difference. If you do update to 5, them the moveAreaRadius and HyperspaceExitRadius will always be pulled from the planet/star entity file."
Invalidate a significant tech tree for the Shadows and Vorlon who until this change had significant advantages on where in a gravity well they could jump from? I've not tested this since 1.83 came out but have others observed this change?
