Powder Toy Version: 70.1
Windows: Win XP (32-bit)

Problem:
  When you place signs anywhere in the simulation, it erases some walls near by the placement of the sign.

Opinion:
  Incredibly annoying as I try to simulate the pressure in a certain pipe design.

Oh, I thought it wasn't known so I posted it here.
Do you know when this bug would be fixed?

Then that is very good news then if its going to be fixed soon.

I guess for now I'll avoid using signs to save myself a bit of a headache until then.
Thanks for informing me.
