Yes, that is really weird! You had the same course and the same role  
on both machines?

One thing that could have an influence here is the cache. To reduce  
the number of transactions between servers, LON-CAPA for a limited  
time stores such things as associations between internal identifiers  
("symbs") and resource URLs and versions. Caches affect all processes  
on one server. Looks like we might be writing garbage into those when  
it comes to which version of a resource to pull up.
