We have a piece of code here which has happily worked for years just decide to start playing up. In investigating the problem we have noticed that we are on version 14 of the code and when looking back to see what the previous version was like noticed that we can only go back to version 10 . Version 11, 12 & 13 seem to have dissappeared.
This exact piece code is working fine our non-production environments . The code is probably one of our oldest bits as it is an include which is used to word out date variables.
We are all stumped at the moment.
