Tutorial Crash Fix

  • Addressed a reported crash that could occur when placing a tower during the tutorial on some systems

  • Added defensive safeguards across the tower placement pipeline to prevent crashes caused by failed resource loading

  • Tower placement now gracefully handles edge cases instead of crashing — if something goes wrong, gnosis is refunded and the game continues

Tutorial Quality of Life

  • ESC now exits the tutorial — press Escape at any time during the tutorial to skip it entirely

  • Skip Tutorial button is now visible from the very first tutorial step

  • These changes ensure players always have a way out if the tutorial causes issues

General Stability

  • Added null-safety guards across all 13 tower initialization scripts

  • Fixed a bug where placed towers didn't properly mark their grid cell as occupied, which could allow overlapping placements

  • Improved error logging throughout the tower and card systems for faster future debugging

  • Hardened enemy targeting to filter out stale references

We're aware this crash has affected some players since launch and we sincerely apologize for the delay in addressing it. The bug could not be reproduced on our development hardware, which made it especially difficult to track down. This patch adds comprehensive safeguards that should resolve the issue. If you continue to experience crashes, please reach out — the improved logging in this build will help us pinpoint the exact cause.
