I've found a bug by a mistake. Here is the instruction to recreate this effect: 1. Be a fieldop. 2. Find a dead body of a medic from your team. 3. Throw an ammopack near this body. 4. Dress as this medic (class switch). 5. Pickup ammopack. 6. On button 5 you will have medipacks AND ammopacks. Here is the proof: http://przeklej.org/file/A7YXP5/wtf.dm.84.zip UPDATE: It works with every class when switching from fieldop (ammopacks available on button 5). It doesn't work when switching from medic to any other class (no medipacks on button 5).
