[rules-users] Optaplan6.0.0Beta1:chaining-simpleScore OK, DRL Score corruption - VRP time windows

[Geoffrey De Smet]

Phreak isn't ready for general consumption yet :) We're working hard to 
make it ready though.
Regardless, the fact that Phreak doesn't expose this issue is a coincidence.

There's actually a potential issue in OptaPlanner:
   https://issues.jboss.org/browse/PLANNER-158
Given the recent uptake in VRP implementations, I 'll try to give this 
priority in the next month or so.

To fix your problem you can either go alternative B) or use the 
described workaround hack to get alternative A) to function properly.
