OK the picture alone was helpful to find the bug!!,
a fix should be online tomorrow or as soon as possible, thank you.
Also, achievements can be skipped. I opened my test save at 75 KB of DPS but the information box said "achievement unlocked" for three DPS-related achievements (none of these requiring more DPS than 64), one of these being "Data worm", which requires 8 KB of DPS. I didn't take a screenshot though, and I didn't modify the list of unlocked achievements manually.
