Acts are not started with autogenerated engine
The current implementation of the autogenerated engine the event start trigger is only evaluated, if the act start trigger condition evaluates to true in the same step. from OSC 1 standard perspective the act has a state machine, which changes from standby to running as soon as the start trigger fires. so it's only necessary for the act's start trigger to fire once and then in all subsequent steps the event start trigger needs to be evaluated.
