Open Beta Update 1.5.4 - Workers Experience, Store Sales, and More!

Hello Miners!
Update 1.5.3 Open Beta is here!Try out new content before the release.
What's new:
- Workers Experience
- Store Sales
- Retraining Workers - choice of specialization
Workers Experience
Workers can now get more skilled with time! For each working day at your gold mine (counted on midnight), they gain +1% performance. When the worker reaches maximum performance for a particular Tier, the Upgrade option is unlocked, which allows upgrading the worker to the next Tier. The Upgrade itself doesn't increase the performance.
Store Sales
Once in every 1-3 days, a random part in each store will be on sale. The sales are independent for both stores (machines and equipment) and can happen on different days. Items are on sale only in physical stores (in other words: there will be no discounts on the laptop).
Discount range:
- Machine Store - 10-25%
- Equipment Store - 15-30%
Players will be informed about the sale via prompt (upper left) with information about items name and discount.
Changelog:
- Added Store Sales (described above).
- Added Worker's Experience (described above).
- Retraining Workers is no longer random. When selecting the Retrain option, a specializations list will appear. Each specialization has a different price - the more complex the machine, the higher the price. If the worker was on a higher Tier than the 1st one, he/she will lose the percentage of performance equal to one Tier.
- Updated DigTube videos.
- Reworked particle effects of campfire and machines smoke.
- If not used, Batteries now lose durability during winter.
- Added possibility to order drill services on random spots via Laptop.
- Icons of broken parts now also appear over broken parts, which lay on the ground.
- Fixes of achievements, which rely on statistics.
