AITAH?

Energy FP&A analyst here. I work for an early-stage project developer and we partner with IB's in order to market our projects to prospective buyers. Part of this marketing effort entails the creation and maintenance of financial models for the projects we are actively working on.

My job as an analyst is to create an internal model for a project using our preferred formatting, then compare it to the IB's model, effectively using the IB model as a sanity check (energy project modeling can be tricky). We recently received a model, and after doing a deep dive, I noticed a few errors that needed to be fixed. Though I can fix it on my own, my bosses prefer the IB does it, and as such I emailed the VP on the deal and later received a fix from an analyst at like 9:30pm on weekday. There was another error I found, and I again emailed the VP, receiving a fix from the analyst at like 7:00pm but this time on a Sunday night. Since then, I have found a few more.

I mean yeah I know you bankers are expected to work long hours, but I feel shitty asking for fixes on a model that I can do myself, knowing an analyst my age has to work on them until the wee hours. Golden rule you know.

Should I now on just do the fixes on the IB model myself and notify the VP about the fix, or continue letting them do it?
