Steps to Replicate

The error appears randomly, but, it has already been proved that it can happen due to macros, such as the Status Macro, for example. One should be able to replicate it by doing the following:

1. Create a page and include some Status Macros.
2. Have more than one person editing the page at the same time.
3. Hit Publish - You shall run into the problem.
