This of course is the kind of thing you have to do if you don't want to run your RPGs in the default setting the game comes with (it's Eriador, the OTHER side of the Misty Mountains for those who don't have TOR 2e) 😉

The CSUAC trees are part of the free third-party resources you can download and install for use with CC3+. The process is not straightforward, however. If you want to try, you can find the links on this Forum information topic.

This used to happen with new sheets you'd created in any map. If you didn't put anything on the sheet, it would be deleted the next time you reopened the map. That was changed in an update a long while back, and while it does solve the problem that if you don't use it immediately, you'll lose it, it does mean most maps now end up with far too many sheets in, because nobody's ever going to remember which sheets haven't been used in a given map. Plus there's always the danger you'll accidentally delete some critical sheet by mistake that has something on you'd forgotten about if you try to do a cleanup manually.

It would be excellent to have the same possibility to remove excess Sheets at the end of a map, just as you can with Layers, currently. Not sure how practical that would be from a programming perspective though.

You're working well here Remy - only another couple of thousand maps to go 😉

Oh, wait, no; that might have been a dream I had... 😁

Thanks for the additional information on your map @NZgunner - much appreciated!

It's so difficult to be sure what the palaeoclimates were for specific periods in the past, as the evidence is commonly very incomplete, and needs a lot of extrapolation. There are suggestions for what may have been happening in certain areas at more specific times though, so if you wanted to tie down to a specific 175 Mya date, it might be worth checking through the available literature.

It's not certain that modern climatic zones and effects are necessarily a suitable model to copy for the geologic past, unfortunately. There's evidence for a lot more free carbon-dioxide in the atmosphere than modernly at times in the Jurassic, for instance, partly hence the somewhat warmer temperatures than today too, in all probability, and the apparent lack of major glaciated regions.
