Vase mode does not slice if height modifiers with different flow ratio are present

[fionnb]

Is there an existing issue for this problem?

• I have searched the existing issues

OrcaSlicer Version

2.2.0 b2

Operating System (OS)

Linux

OS Version

Arch Linux

Additional system information

CPU: Ryzen 7840U
RAM: 32G

Printer

Prusa XL 5tool

How to reproduce

1. Enable at least two materials or extruders (may or may not be a necessary step)
2. Enable Vase mode
3. Add a height modifier and change the flow ratio on that
4. Try to slice

Actual results

An error message appears, informing you that you "can not use multiple materials in vase mode". The slice buttons stays inactive until the height modifier is removed.

Expected results

The error should not appear, unless an actual material change occurs and not just some random modifier like extrusion factor or the like.
