+# machina-factory-bugcase
+
+A demonstration of a bug in machina v2.0.2, where a child FSM factory is called multiple times when specified as part of a config object.
+
+What should happen:
+
+```
+(fsm.0) Parent state 1 reached
+Creating child
+(fsm.1) Child state A reached
+(fsm.0) Parent state 2 reached
+Creating child
+(fsm.2) Child state A reached
+(fsm.2) Child state B reached
+```
+
+What happens instead:
+
+```
+(fsm.0) Parent state 1 reached
+Creating child
+(fsm.1) Child state A reached
+Creating child
+(fsm.2) Child state A reached
+(fsm.0) Parent state 2 reached
+Creating child
+(fsm.3) Child state A reached
+Creating child
+(fsm.4) Child state A reached
+(fsm.4) Child state B reached
+```
