Hi, A simple one - I've made a Keyboard PCB with about 60 switches I have the switch PREFIX called it's character i.e. A, B, C, D, etc THis woked well for 3 revisions My latest keyboard failed. Numbers 1 to 9 all appeared on the same net. Something has changed in EASYEDA in the past few months. If I change the switch Prefix  to N1, N2, N3 instead of just 1,2,3 then I can make my board work if i change the prefix back to 1,2,3, the nets all tie together for the numbers Note, I'm now aware i've made an error by changing the prefix for each item, But, each prefix is unique so should function as a name also
