I had a similar problem where I placed a chest under some stairs (pretty close to the supports). I can hit the "E" to open it but there's only one small corner where I can do this. The rest of the chest won't show the E to open message for me.
Yes, that is happening to me as well. I placed a chest underneath the stairs, one near the ramp and the other near the support, and now having problems opening it because I have to find that perfect spot to get the "E" to open icon to pop up...Looking forward to the fix! Thank you.
