I tried to reproduce a similar situation here, but I got the expected and correct results. Those three documents that you saw in your first search result should be the first in your second search result (unless the index changes or the sort changes ) when fq on that specific category. I'm not sure what is causing this problem. Can you give me some more information like the field type configuration for the ctype field and how have configured field collapsing?
I did find another problem to do with field collapse caching. The collapse.threshold or collapse.maxdocs parameters are not taken into account when caching, which is off course wrong because they do matter when collapsing. Based on the information you have given me this caching problem is not the cause of the situation you have. I will update the patch that fixes this problem shortly.
