# Bug description
There can be clicks during concealment in MDCT-Stereo (stereo >= 48kbps). This bug was recently introduced as we used the same error pattern in our subjective verification listening tests where this was not observed.
Clicks are clearly visible in the fixed-point decoder output:

# Ways to reproduce
```
./IVAS_cod_flt_ref -stereo 48000 48 ap03a2s05.wav bit
eid-xor -vbr -fer bit ivas-codec/scripts/dly_error_profiles/ep_5pct.g192 bit_err
./IVAS_dec_fx stereo 48 bit_err out_fx.wav
```
Error pattern and input signal will be shared separately as usual.
