Hi,
I had a project that used a hierarchical sheet from Modules folder and it worked fine in previous nightlies, but between sometime 2 months ago and now it broke.
I made a test project with subfolder called “SUB” and created a sheet called subsheet inside SUB, so the path is “SUB/subsheet.sch” and it displays and works in eeschema, UNTIL I close the project and reopen, then it says cannot find subsheet.
this is mostly a support forum (Only a handfull of developers frequent this forum.)
