Serious BUG of UiPath?

We encountered the phenomenon that the 2nd time we call Find Image / Click Image / Image Exists … all those image related activities in a package, we always encountered the errors “activity timeout”, or “cannot find the image”. If we remove or disable the 1st activity, then the 2nd one would be working fine.

According to our testing, it has been confirmed a bug on UiPath Studio, from version 2018.1.1 to 2018.2.1 at least, may be also exists on more earlier versions. Since it’s a basic feature of UiPath, please make sure it’s really stable before you release “Stable” edition.
