[OpenCities Map Update 3: VBA] xft.FloodRegionOp not working any more

We use the xft.FloodRegionOp object (in VBA) to do flood regions operations.

This object worked fine in the old (XM, v8i SS2/3/4) Map versions but seems to be missing or invalid in the OpenCities Map XFT API.

As soon as this object is used in code the "ActiveX component can't create object" error message is displayed:

These two lines of code can be used to reproduce:

Dim oFloodRegionOp As New xft.FloodRegionOp
oFloodRegionOp.SetDataPointPrompt floodRegionOpPromptTypeFirstPoint, "First point please..."

Any help appreciated!
