what file type is the resource? I’ve seen this a few times within ctrlr standalone itself running ctrlr 1590 on a mac, I’ve only seen it with jpgs but for the most part that’s all I’ve been using in my most recent areas of panel development.. I haven’t looked yet to see what happens when I export (cringe) I hope this works ok if it doesnt but I find a work around I’ll repost here.
When the image “disappears” it literally is gone from the resource list, so I have to reimport it again. Seems as if things work ok then after re-importing, then saving and closing the panel then re-opening it, even on a different machine. I’m saving the panel as a bpanelz (with resources).
