look at the file ext_tables.php

I guess there is a line like that:
t3lib_extMgm::addToAllTCAtypes("tt_content","tx_someext_somefield;;;;1-1-1");

just remove that line, and insert the following line after loasing the 
tt_content TCA with "t3lib_div::loadTCA("tt_content");":

$TCA["tt_content"]["types"]["list"]["subtypes_addlist"][$_EXTKEY."_pi1"]="tx_someext_somefield;;;;1-1-1";

It would've been like that anyway if you had set the option "Apply a set 
of extended fields" in the frontend plugin section of the Kickstarter.
