I think it goes something like this: there was a 15:1 consolidation of shares, meaning that in your new holding you would have one share for every 15 you owned before.

given that the market cap stayed the same over the trading halt, as soon as trading recommenced that one share was worth 15 times the price of a prehalt/preconsolidation share ie the share price went from 0.001 to 0.0015 (but now with only 1/15th of the amount of shares on the register and in your portfolio).

that's changed now though as there are more pips to trade on. I had the MEMDC thing there for a while too (I guess the C might stand for consolidation?) but it's back to MEM now. I'd say it would just be a case of your platform being slow to catch up.
