Zerstorer crashing on quakespasm

Hi, I was replaying Zerstorer and found 2 very ugly bugs: in Zer1m3 silver key doesn’t appear (the one near the death knight statue) and on Zer1m5 once I’ve took the Sanguinoch and it kills enemies the game crashes. Any fixes for this?

Oh I’ve forgot: I play on Quakespasm spiked

Are you playing the initial release, or using the 1.1 patch?

1.1 patch, but I’ve noticed that in VkQuake this does not happen, and if I remember well even in classic Quakespasm.
