hmm... I have been trying to recreate this and I cannot.
Sakura-chan is very complicated... she has many RNG triggers that do different things at different places.
Are you referring to losing regularly to her, or when she finds you at Jackie's area and gives you a handjob, or the Perfect Lust Gaze encounter (starts out where she says you are avoiding her)? If it's the PLG encounter things get even more complicated... are you able to tell me what you did right before the encounter?
In any case, I will be releasing a new update on Sunday and I have edited her code since then. There is a chance that I will not be able to recreate this anymore and it may be resolved on the next patch... You may need to start a new game however :(
