I just got 2 extra vegetations yesterday and have the same problem. Quite frustrating to see that it might take weeks until the problem gets fixed. One thing that puzzles me is that all extra vegetations I have installed under Vue 2 work fine with Vue 4.03. I have not re-installed these vege species but copied the whole plant directory just as indicated in the supporting documentation. So installing the extra vegetations using Vue 2 or 3 and then copy the new plants into the Vue 4 plant directory might be a workaround for this bug. Unfortunately I have deleted my old version and don't want to reinstall it ... Christoph
