No, she was maxed. Her and Julia were my first two girls maxed out. I checked their points on the Staff page. It just seemed to happen when I switched tiers with Julia - to take tier 5 guests instead of 4. Amber had never had a bad interaction in the restaurant up until then (unless I clicked the wrong meal of course).
I'm going to start from scratch when the next update comes out. I'll keep better notes then.
750/750 XP provides 60% satisfaction at Level 5.
You also had a total of +20% and yet you somehow got 57% (not even 750/750's amount!), instead of 80%.
Subtracting the 20% leaves just 37% gained from your skill, which does seem distinctly like the sort of amount a Level 4/low XP Level 5 skill would achieve.
There is no way that I can think of to reach a number that does not end in a 0 or a 5, other than the skill XP not being full.
Weird.
To test this, I wonder if
larry5168,
Sycho or
S3pHiroTh can check the % gained by a low XP Level 5 skill.
If it's anything similar to 37%, I think that's your answer: Low skill level, not bug.
If you'd only just upgraded to Level 5, then it's completely understandable that Amber hadn't failed a guest before.
They were only Level 4 guests, their satisfaction % is lower.
Level 5 guests are more demanding & harder to satisfy.
(EDIT: Forgot to mention - suggestion - to compensate for my above suggestion, and not make the game too easy - have random failures of some kind that are clearly marked as such. for example, in the restaurant, maybe a meal randomly gets ruined because the food is spoiled.. something like that. That get's mitigated by you doing the QA office thing or some other variable you can manage.)
No thanks.
Seriously, absolutely no way would I like to see random failures introduced.
If I fail, I want to be able to improve and not fail again.
Not for me to be the best I can possibly make my character & it still fail, cos RNGesus said so.
Fuck that.
