-The sniper stays charged and wont fire when I let go of the fire button, I have to switch weapon to leave walk mode.

Reproduceability: Sometimes

i just had this happen right before i went to bed... it seemed to happen when i let go of the charge button right as it fully charged.

This issue is repeatable 100% following these steps:

Steps To Reproduce:
1. When the user launches FE:L on either map
2. selects a Sniper loadout
3. equips the Sniper Rifle
4. holds down the Jet/Ski button (Right Mouse default)
5. while still holding Jet/Ski, press the Fire Weapon button (Left Mouse default) - This will cut off the jets due to charging the rifle
6. let go of jet/Ski once the jets are cut off
7. hold Fire Weapon until the Sniper Rifle just hits fully charged (The front of the rifle will be enveloped with blue plasma)
8. let go of Fire Weapon

Observed Result:
The blue plasma shown on the front of the rifle will continue to show until the user fully charges and fires the  Sniper Rifle again.  Until the weapon is fired again, the user is stuck on the ground, although holding right mouse button seems to make the walking pick up speed.  Once the weapon is fired again, the user dies or the user switches weapons this issue resolves itself and normal play continues.

If a video is needed demonstrating the timing, let me know.

I've had that happen to me a few times, will test if I can do it using Tristan’s handy steps.

I wasn't able to reproduce this exactly with the above steps, but I have seen this before and got it to work once with a mixture of these steps and jump+jet up combo.
