Interesting. Since I wa not able to replicate your error (at least not with Tomoe Gozen and Miyamoto Musashi), please give me some more information. What I need is:

- Unit size setting
- Were you using the ancestral unit as a General unit
- Exact time of the CTD (as you said: when zooming in or attacking, right?)

Btw, low details shouldn't change a thing, since there is only one level of detail implemented for
the ancestral units anyway^^
Please tell me about your observations,
regards,
