Didn't play since 1-2 years. Did Fatshark fix their update schedules?

Hello! Yes, I can confirm that this issue has been fixed. We should not expect ridiculously large patch sizes at all in the future.

In general, we should expect that most hotfixes will be a few MB in size. Big patches can be up to around 4 to 5 GB but will be less than that on average. No more 25+ GB patches, for sure! fingers crossed
