Suite step 7 merging freeze many times
 

I have about 30 styles in my dev forum.
each styles has many edited templates,

and when step 7 there are a lot of freeze, the step7 stop many times for each style id but not complete.I think more than 20times.I still havent complete yet this step7.
each time I have to refresh and lower the startat number.(finalupgrade.php?step=7&startat=145#end) startat stuck from number30.

I wonder if I have more than 100skins in future for vb4?
this will be totally a mess.
