Here's another one. I cloned a large route, Cajon Pass Alpha by Tim Zorn. Note that this tour de force is not "alpha" quality. I've been all over it and added AI trains, etc. It's unbelievable. I started working with this scenario and BOOM! TempDump 0xC0000005. After my previous experience with Scenario installation from the Workshop (see Subscribing To Workshop -> Temp Dump 0xc0000005 Access Violation) I decided to to an integrity check on the cloned route with my awesome Araxis Merge tool. I discovered that the ...\Networks\tracks.bin was much smaller in the clone. A content comparison showed that the cloned tracks.bin was missing almost 3 megabytes of data! The original is 8.074 KB and the cloned one is only 5,619MB. Totally corrupted.
