I have completed Diggy's 6th birthday. It shows that I need 3 more pocket computers to complete the achievement. I have been through all the rooms several times and cannot find any more pocket computers, did this happen to anyone else? and how to get the last 3 I need

StatsNerd

pixel_player31915728 Wiki states that there are 74 pocket computers available in total (46 in the story mines and 28 in the 3 challenge mines).

The achievements page shows how many are required for each level:

4+5+6+7+8+9+10+11=60. 46 would be gained in story mines, the remaining 14 would need to be collected from the challenge mines.

In order to complete Event Achievements where items are collected (say it like that as there are some Achievements requiring cooking recipes) doing at least part of the Challenges is always required.
