Strange, as the waring show that it can not be loaded due to compiler error
one thing, if you use templates from another project and you used custom actions in it, you need to have those actions in the target project
Here is an example of one of broken ones - "Reachable".
It is very simple as you can see.
If create new Template (in old project) of two empty states connected with one FINISHED transition and import it to new project - it is broken as well.
UPD: If I Export/Import that new one with all of them - broken ones are still the same (including this new one)
+: If i rename/duplicate one of broken ones in old project - they will be broken too
+: "Building" Template is completely empty with lots of variables (I use it as a storage) and it is broken too - so it is definitely not actions in these FSMs
UPD2: Tried to import them into completely fresh project with only Playmaker installed and same ones are broken in same way
