Investment appraisal fails when demand is equal in 2 consecutive years in (a slight adaptation of) the simple model #1115
Description
Describe the bug
I modified the "simple" model so there are more milestone years. If two MSY in a row have the same service demand input (RSHEAT in this case), investment appraisal fails. It appears to calculate NaN for the metric.
A clear and concise description of what the bug is, including error messages.

Expected behavior
I can't see a reason why investment appraisal should fail - it should be fine.
