I have noticed a serious (if so) bug between v3.3.1 and subsequent development versions (possibly also a variant of v3.3.0 that was not included in the v3.3.1 release). The bug, if such it is, seems to relate to a trigger.

Platform: MacOS v10.15.5, MacBook Pro (13-inch, 2016)  
Vassal: v3.3.1 (works)  
Vassal: v3.3.1-152 (fails)  
Module: C&C Nap v3\_43r02T (not released, see files section below)

Expected behaviour:  
A module attempts to trigger a set of keyboard commands that move a card from a hand window to a Zone in a map window, setting a number of global and dynamic properties in the process. The trigger is initiated from one action linked to a multi-action button.

Error symptoms:  
When executed directly under Vassal v3.3.1-152 (as opposed to replayed in a log file), the module behaves as if the trigger did not fire. Yet the status of related properties is correct for the trigger, as demonstrated by re-attempting the action under v3.3.1 with no other changes. The fact that the re-attempt works under v3.3.1 is evidence that the trigger did indeed not fire under v3.3.1-152.

The equivalent function in the current release of C&C Napoleonics (v3.42) does work in both Vassal versions. C&CN v3.42 has the same button/trigger but without conditions controlling the trigger and with only one keyboard command executed by the trigger.

Files:  
Evidence can be found on this dropbox folder. Explained further below. [dropbox.com/sh/wso0aqo93yuo … KuEGa?dl=0](https://www.dropbox.com/sh/wso0aqo93yuog0r/AAAqEfqymIMDKaB885ssKuEGa?dl=0)

C&C Nap v3\_43r02T.vmod: Experimental/development version of the C&C Napoleonics module.

rolica test.vlog: Starting demo log. This was created under Vassal v3.3.1 and re-plays as expected under both Vassal versions.

rolica test2.vlog: 2nd demo log. This was created under Vassal v3.3.1-152 as a continuation of the above. It fails as commented in the log file.

rolica test3.vlog: 3rd demo log file. This was created under Vassal v3.3.1 as a continuation of test2. It succeeds in completing the action that failed under v3.3.1-152 (pressing the appropriate Multi-Action button in the “Allies” hand window).

rolica test-redo under -152.vlog: Same as rolica test.vlog but created under Vassal v3.3.1-152. Action button in allies hand window fails to trigger the card discard. Replay under v3.3.0 shows the same failure.
