Hi all, I am fairly new to XOD IDE, and was doing the tutorial when I was on 009-pulses on my PC when the simulation button got me in a loop where whenever I pressed the simulate button it just got stuck on [building…]. Even on my iPad and the browser IDE it was doing the same. I went to ChatGPT to try and figure out why, but I just went around in almost circles, reinstalling and deleting and reinstalling again. I thought maybe the servers were being weird so I thought I’d reach to this forum. Thank you in advance.

I’m seeing the same issue. I sent a message to one of the original developers, but I don’t know how much they are still paying attention since development stopped with sanctions against Russia due to the war with Ukraine.

I happened to notice simulations are working again.
