Mismatch in credits for CustomModuleAttainment

[valtterikantanen]

Check id 'hy-opinto-128526453' from the importer-db's attainments table. This CustomModuleAttainment has 10 credits, comprising one CourseUnitAttainment and three CustomCourseUnitAttainments with the following ids:

'hy-opinto-99938336', 'hy-opinto-100270492', 'hy-opinto-100420310', 'hy-opinto-101806146'

In the sis-db, 'hy-opinto-128526453' is a study module and the total credits are correctly listed as 10. However, when we pull up the details for these four attainments, only 'hy-opinto-101806146' (the CourseUnitAttainment with 7 credits) is found, leaving us short of 3 credits.

Additionally, there's a discrepancy on the Oodikone student page: the student has 182 credits for the bachelor's degree and 120 for the master's, but the total shows as only 299 credits. It seems very likely that the missing 3 credits from the sis-db are the same missing in the total credit count.

the attainments may be old and thus weird.

also, let's check with a simple script or query if there are many cases where actual credits do not match the 180 or 120
