M50 Ontos

[SandyC 2]

I would be grateful if anyone could help me with this eccentric machine but favourite of mine. I have searched the forum, but there is no post that I can find on this. I have installed the M109 and M50 Ontos from RebelRyder and the Update Artillery files. The gundata files are sorted out. The M109 blasts away merrily, but while the machine gun has fired, the M50 recoilless rifles are mute. Is this because the SF1 coding does not allow multiple guns firing, or do I have another problem with it? If anyone else has managed to get the Ontos lobbing multiple rounds across the Perfume River or into the Citadel, I would be grateful for a steer on how to fix it. I was wondering if maybe I should neutralise five of the six barrels. It is not vital to the mission I have constructed, but it would be good to have the extra immersion I am getting from the M109 and M107. Many thanks in anticipation.
