GTA V: I hope this heads-up will save someone a lot of wasted (actual) time and (virtual) money

[Shampoobra]

3. NEVER MIND ... after some research, I discovered it's a major glitch in the game

This could turn into a real news item if Rockstar doesn't fix it quickly.

From what I can tell, Rockstar is currently learning that GTA V is messed up in a very major way. It's a franchise that centers itself around cars, but buying and upgrading them is like flushing money down the toilet...

Vehicles disappearing from the GTA V garage, or losing upgrades

Question: I upgraded my car and then completed a mission, and now my car is gone. Help!

Question: I've lost some of my upgrades after completing some missions and then checking my garage. What should I do?

Answer: We have received some reports about problems with cars and garages, particularly after upgrading and then completing a mission, and are looking into this now. Unfortunately, we do not currently have a workaround to recover a car if it is missing.

Until they fix this, there's no reason to buy cars, upgrade cars, or buy garages. What a major setback from an otherwise outstanding game. It knocks my opinion of the game from an A to about a B-.
