Thanks for posting. If you are seeing the Designer crash you can reach out to our Support Staff directly through this contact form:
We definitely want to hear about any actions that cause the Designer to crash with a grey screen.
For this specific issue, though, it looks like transforms within the interactions panel are ignoring % based values. I’ve reported this to the team and we will investigate this — we hope to have a fix soon.
For now, though, you can use VW/VH to achieve a similar affect until we can get this resolved:
I didn’t realise I could get in contact with staff directly so that’s fantastic.
Most definitely – please feel free to reach out anytime you have questions or thing you may have found a bug.
Regarding this issue with % based values in the interaction panel, our team has found the issue is working on pushing a fix now. The fix should be live by today.
