Since I updated to OG 7.17.3, all my custom stencils are not working anymore. I can see all the stencil files in the stencil window but I the single elements are not loaded anymore. There is just the spinning wheel is shown but not any graphic elements.
If I right-click on the stencil file, I can even edit the file. When I do any changes to the file and try to save it again, OG is asking if the file format should be converted to the new file format. Regardless if I say “yes” or “not now”, after closing the file it is still now showing its elements in the window. I hope this is somehow understandable.
