Using a surface pro with windows 8.1 and an up to date version of Flash CC.
When erasing a pencil line with the faucet tool, it will also erase random nearby lines and even fills! Pressing undo will bring back the line that you meant to erase, but will NEVER bring back the lines that were randomly erased! This happens almost every time I use the tool!
I have found a post on this forum with the exact same issue, but for Mac. But I have the issue on a Windows machine.
