NULL attrs after @restart

[psc943]

So, I built TM3.2 on Ubuntu 14.04.5 (x86_64), it compiled fine. The game had been running for maybe two days with no issues whatsoever but then I did a @restart, and when the server finished starting up, I discovered that a couple of functions were no longer working. I checked the object they were defined on and discovered that while the attribute name still showed up on an examine, the text with the code for the function was gone. Not sure what had happened, I restored from backup and continued working for several more days before I did another @restart, and this time when the server finished rebooting, the name for #0 had disappeared.

Any idea what might be causing this? I would really like to continue using TM for my project but I am afraid to do anything now for fear of what I might lose next.
