Update to not lose experience

[Gnubond]

If I have a master or a 'not just another fighter with great experience, I can upgrade tracks, body or arms without changing experience?

[Zarel]

Yes; recycle the unit.

For more information about that, I reccomend that you take a look at:
Unit Experience Table
And, for better knowledge about general unit behavior, you should read this as well:
Ordering Units

In addition, this should be posted on Help/Troubleshooting - not a real problem, just a reminder
