By any chance, do you remember any particular circumstances of your death, before you spawned ?
In any case, it is a mod code bug, not a map bug.
I do have the same problem, during the test :
no weapon, and nothing appeared when trying to change weapon.
Picking up a shofield, for example, lets the menu change appeared again with only the shofield in the menu.
(So, I really do have no weapon, mod code speaking)
In my case, I was killed by Red,
just before the next round started.
In b2.1, if you remember, you respawned in the next round with all your items, even though you were killed.
In b2.2 or after (the "bleeding edge" version), I remember I have changed something about resetting weapon equipment (mod code speaking) when killed.
(to SG members :

So, it may be the reason why you respawned in the next round without any items.
Of course, you can count on me to try to fix it
