Hi, south brilliant,

This feels like Tolerant Selection is on, but your screen shot shows it is off.

I just answered a question that might be connected somehow. But sadly, I have no solution for that.

Thanks for pointing out that you are on Windows, as I saw it elsewhere also mentioned to appear running Windows. I have problems recreating it on Mac.

Since your model looks more complex than two cubes, I can look into it; please just use the object as a c4d file. Thank you.

I'm unsure if that pushes anything forward, but if you would like to check, please get in touch with tech support.

Sorry for the extra effort.

My best wishes

Hi Benedetta,

After checking it here and reinstalling the previous version, I can't reproduce it on a Mac.

Thanks for pointing out that you are on Windows, as I saw it elsewhere also mentioned to appear running Windows.

The Pen tool would be the only workaround for now; having more work is not fun; I get that. I hope it is fixed ASAP.

I'm unsure if tech support can help, but I just wanted to let you know if you want a second opinion.
