Question First time Modder need some help on debug

[Kai5879]

I'm writing a mod to add some new events for Sebastian(maybe Eliot and Shane too afrer i solve this problem)because i found the life after marriage is not as "interesting" as i thought,the dialogues are almost the same,and some mods i tried only show dialogues with no animation or characters moving around(the kind that fade in and fade out),and I tried this...when running the testing version SMAPI keep shows red,here's what log shows:

[00:09:02 ERROR Content Patcher] Patch error: (CP)EventsPlusSebastian > Load Maps/Custom_FarmHouse has a FromFile which matches non-existent file 'assets\Maps\FarmHouse.xnb'.
[00:09:02 ERROR Content Patcher] Patch error: (CP)EventsPlusSebastian> Load Maps/Custom_BathHouse_WomensLocker has a FromFile which matches non-existent file 'assets\Maps\Custom_BathHouse_WomensLocker.xnb'.
[00:09:02 TRACE Content Patcher] Requested cache invalidation for all assets matching a predicate.
[00:09:02 TRACE SMAPI] Invalidated 0 cache entries.

SMAPI log parser - SMAPI.io

it's only the 1st class to make and it's really hard for 0 base programming person(and not native English-speaker)...I would like others to try this mod afterall.Really need your help.
I have the assets file included "Maps" and .xnb in it.Didn't know why it couldn't be found.T T
