Grit City,
Since you mentioned a DCS240, did you set it not to use 'expanded slots' (or
whatever name they use for the more than 120 slots)?
Those slots beyond 120 (up to 400) work differently and the code might not
do so well there. They are working towards understanding the extra changes
for that, but I'd turn it off in the command station (it is a OpSw thing)
just to keep things simple.
