HELP - former TAW holder from Europe with now

Hi HC experts,
didn't follow closely the development of TAW and AMAL since I invested in this stock for long term reasons.
I'm based in Europe and just followed up the entire merger due to some stock in my depot called "All.Mineral ASS. DEF" with ISIN AU0000031270. Used to have a value of EUR 4000 however shows since entire January '19 a value of EUR 0.
Now I'm very confused: Did I miss any deadline and got squeezed out and have now nothing in hands anymore?
Tried to understand the shareholder scheme but not all clear and didn't find a proper answer to my issue.
Did anyone experience similiar issues or even better can provide me with a solution/clarification?
Cheers and thx in advance 
Marv
