Not exactly: in my playthrough i didn't relased Kira, i stole the wallet 2 times (caught and succeeded), used the wallet to blackmail Eric into leave everyone except mom safe, and after some time and some progress with Alice and Kate (bought and used at least one weed small pack) i had enabled the Kate conversation for getting rid of Eric.
i did never state thatthere are no other ways.
i said the main way. and then atleast one that works and does trigger it again. and thanks for info, i believe many ppl find it usefull, lots ppl gettin stuck on every step here =)
about the *bug* that ppl having with lisa lessons when they get rid of eric. did find the source of it. its not a bug,
ppl use the cheat to get rid of eric, instead of just starting war with him, wait for wallet (accusation in stealing money) and then going thru quest line.
the cheat is just a 'switch' for a flag. and the default spot for the wallet oportunity (if you would start with a war from begining) will trigger before you start lessons with lisa, so the cheat will rollback it (ikaruga could aprove it)
i did test yesterday, did use cheat to get rid of eric first, and next morning he was gone from game, and lisa lessons roll back to kissing (tho kira still ready to come at nights)
doing quest did not roll lisa back to kissing lessons) *unless if it just me being lucky*
