Hi Michael,

In MoI4 beta, Feb 2018:
There appears to be a bug when changing the color Style of one or two curves that are to be blended again.

1. Draw two red curves that are to be blended.
2. Select the two curves, and blend them. The blend is red.
3. Delete the blend.
4. Change the color style of the two curves to blue.
5. Select the two curves and blend them. The blend is red.
For these two curves, blend is stuck on style red.
Replace the first curve with another curve, of a 3rd color style, next to the first curve. Blend is "stuck" on style red.

Also, the blend is stuck on the first two ends blended. A second Blend does not work between different selected ends. The first blend keeps reccurring.
(Maybe one of the reasons I commented about selecting "close to ends" of curve, with Blend the other day.)

I came across this while testing clothoid created between two end points of curve(s), versus Blend.

(Also I see that Blend does not work between the ends of one open curve, in either MoI3 or MoI4beta.)
