L4d2 doesn't work as expected

[maclarens]

Great plugin..but
replaces only sometimes if messages are from different plugins and only 2 rows
not replacing if same plugin message center..allways one row
example: i open prize box and see u win katana
and other player open prize box..and him replacing in one row all messages..cant see what be before. etc for other plugins..
ps: possible divide all center messages from any plugin? messages one row even if its same plugin.
