If you have found an issue with ACE3 please make sure that ACE3 is really the cause of the problem. To do this try to reproduce the issue with using only `@CBA_A3` and `@ace` on a newly created mission.
Indicate if the issue appears on stable or development version. In case it is the development version, please also include the commit SHA-1 hash.

<h5>Please note:</h5>
<p>It's not a valid to simply remove <code>@ace</code> from the mod list to confirm that ACE3 is the culprit.</p>
<p>If the error happens when using a <b>third-party mod</b> contact the author of the appropriate mod and report the issue there.</p>

GitHub uses [Markdown](http://daringfireball.net/projects/markdown/syntax) to style the output.

ACE2, AGM and CSE had a lot of features implemented or planned. All of them are or have been evaluated for inclusion in ACE3 itself, and we'd like to port the majority of them eventually. However, due to time constraints, we have managed to finish only a fraction of the job so far.
Please refrain from making requests for any planned or existing features from either ACE2, AGM or CSE. Most of them are already being or have been considered for porting or a rewrite.
In order to avoid duplicates and keep the issue tracker organized, we have created a common issue for [ACE3 Feature requests](https://github.com/acemod/ACE3/issues/414). Any and all relevant requests should be submitted there, where they will also get discussed and evaluated. Before adding a new one, make sure to check the previous entries from the thread and do a quick search for similar suggestions; please don't reiterate requests for features that had already been accepted for inclusion, or those which were disregarded earlier.
