RM 3.0 - Error With Thermo Setpoints

I built a rule in 2.0.9 and I went back into it after updating to 2.1.0 and I get the following error:
app:26332019-05-23 10:36:49.499 pm errorgroovy.lang.MissingMethodException: No signature of method: java.lang.Double.getAt() is applicable for argument types: (java.lang.Integer) values: [0] Possible solutions: getAt(java.lang.String), next(), putAt(java.lang.String, java.lang.Object), wait(), grep(), getClass() (selectActionsTrue)

Here's the rule:

Please just delete the rule and redo it.

Is there any chance that we can see where a rule is referenced, or 'replace' all references to a rule with another?

Completely understand that it may be easier to recreate than troubleshoot these, but it can be painful when the rule to be recreated is a run action within 10 other rules... It's not fun to realize you missed one at 3AM when the lights won't turn off.
