Hi Grievous, welcome to CFC.
![Party [party] [party]](/images/smilies/partytime.gif)
I´m glad that you like CCM and it´s a special honour, that CCM convinced you in joining these forums. Concerning your questions:
1.) This is a problem coming from the animated units and I don´t think that there is an easy fix for it. As far as I know, the first frame of the unit animations is used for that image in the city menue. So each of these animations must be fixed to receive a proper image here and this is not doable for me, but: I´m not a unit specialist. If there should be an easy way for fixing these images known by one of the civers, that read this post, please let me know.
2) Grievous, in your first post you reported here two errors contained in the INI files of the Schneider 75 and the German 77. Thank you very much.

In early betatest versions of CCM the Heavy Artillery was named WWI Artillery. After rebuilding the arty unit lines in CCM the WWI Artillery was renamed to Heavy Artillery and all kinds of WWII artillery were deactivated. Now for the CCM betatest biq v1.3 these guns were "reactivated", but as CCM at present still uses the old main file, here these units have the old names in the linked sound files.
Each of the INIs of both units can easily be corrected by autoreplacing WWI Artillery with Heavy Artillery. The INIs are also fixed now for the next upload of the CCM main files what will be in the future (I still hope, that Wyrmshadow will make a M-109 SPA and Sandris his Immortal -Tom2050 yet has done nice recolouring jobs on the Egypt settler and worker)
And yes, after changing the unit INIs to the correct names you can continue your game.
3) This sounds funny.

Can you please name that boat, so I can have a look on the death animation?
