Report Designer file corruption with decimal line weights

Found this issue when I was updating the line weights for picture objects I was using in Report Designer that were calling Feature Maps from one of my sites. I entered 1.5 for the line weight parameter, and no error or anything was thrown. Saved the report and ran it and got a generic error in the GVS. When I reopened the report it told me there was an error and that the rpx file I had just opened couldn't be found. It also deleted the picture objects and everything I had written in the scripts tab.

This was in the Report Designer version that came with GE 3.11. It could just be an Active Reports issue, but I thought I'd report it since it blew up the entire report and deleted all of my script lines.
