Wanda 4.1 (released on August 13th, 2012) included a bug that was not discovered during testing. This issue can cause incorrect behaviour of some Liquid components, especially Vent (air valve) and Weir components.
We have fixed the problem and a new setup is available from the Downloads & Patches wiki page.
If you’ve downloaded and installed Wanda 4.1 between August 13th and September 6th, please download the new setup and reinstall the software. Installing the Patch is sufficient in this case.
You can check the version numbers of Wanda on your PC. The following versions are affected:
- User interface version: 4.1.1084
- Wanda executables version: 4.1.03
